It is important to keep reminding ourselves that climate change is a real problem for humanity and that each and every one of us contributes to its intensification or mitigation through our decisions. It is a problem that requires solutions, but implementing these solutions involves so much inertia that it can sometimes be painful.
And let's contrast that with the AI hype. It's more the opposite, a kind of solution to problems we didn't really have, but are now being persuaded we do. It would be sensible to invest an equal share of the resources currently being pumped into AI with uncertain outcomes into the complex issue of climate change. And, no, AI won't solve it; unfortunately, it only makes it worse.
> each and every one of us contributes to its intensification or mitigation through our decisions.
I have to disagree here.
This idea of a consumer-level personal responsibility for the fossil energy industry's externalized costs is a lot like the plastic producers shifting blame for waste by saying that it's the consumers' fault for not recycling. It's transparent blame-shifting.
The fossil energy industry pulls the carbon out of the ground and distributes it globally. Then it buys and sells politicians and, through mass media, votes, to ensure they maintain the industry's hegemony.
You only have to look at the full-blown slide of the US into a despotic petrostate to understand the causes of the climate crisis.
Hank Green did a good short video on this: https://www.youtube.com/watch?v=bvAznN_MPWQ
TL;DW: It is important that individuals show that there is a real problem and that they perform actions that address the problem. This demonstrative behaviour leads to social dynamics where more people feel encouraged to perform actions and to drive larger change.
You need to start somewhere.
We know there is a real problem, awareness is not the issue. (I've been aware of it since the mid 90's) It is ignored by large industries and governments. The incessant pounding of the useless drum of individual action continues to go absolutely nowhere. We need government and industry to take action not individuals. I will no longer placate this idea that individual action is at all useful.
The problem is not that individual action is not useful, it’s that governments and companies are actively discouraging it, because every success for climate change is a bad news item. People buying less cars? Climate change win, economic problem. People buying less stuff, consumption down? Huge climate change win, very bad economic news. Even on progressive news outlets they’re doing it.
Here in Europe even before Trump’s second mandate it was clear governments didn’t really want individual action to take off. And it’s even worse now. Because short and mid term it’s a choice between climate and GDP. And western governments and companies are fundamentally incapable of long term action that is painful short term.
I would agree with you, except that the government (eg. in Germany) even battle climate tech when it’s good for the country and the economy. WHO wouldn’t want to be energy independent?
And yet, the Conservative Party in germany once killed the entire solar industry (who then moved to china); and is about to do it again, now! Both times we are losing about 50k jobs in that sector.
The question is: why would they do that, if the economy is oh so important to the conservatives?
> The incessant pounding of the useless drum of individual action continues to go absolutely nowhere. We need government and industry to take action not individuals.
It's the incessent pounding of your drum that goes nowhere, of course. Lots of people acting individually is what makes things happen - including in government. They won't act unless people demonstrate they are serious about it.
> I will no longer placate this idea that individual action is at all useful.
Very brave!
That puts recycling on the "I'm helping to spread awareness by temporarily adding a note to my Twitter bio" tier of action. It's better than nothing, but it's only a little better.
Doing a little better than nothing becomes a big deal when everyone is doing it.
Does it really? Or does it become a panacea to make people feel like they’ve done something when they haven’t?
Perhaps if these non-solutions didn’t exist to appease our fears then there would be more pressure for real solutions.
It becomes moderately better than nothing when “everyone” (not even close to everyone) does it. And there are some decisions (taking fewer/no flights, no fossil-fueled car, etc) that are a lot more effective than others. Personally I try to do my best! But in general, individual actions are dwarfed by systems bigger than them. Even being able to shun cars is only feasible if you live in a city with good public transport, for instance.
It's a lot better; it's actually doing work: Things are accomplished by people acting together. The social aspect is the mechanism of how we do it.
You can see how every step of the way, people try to tell everyone to quit. The fossil fuel industry couldn't design a better plan.
I don't agree. Doing something that's makes very little difference makes you feel better, like you've solved the problem, and soothes the urgent need to actually fix the problem. The city gives out recycling cans, and the populace feels confident that the city is doing something, but that takes pressure off of things the city could do that would actually help but are unpalatable, like shutting down the chemical plant pouring stuff into the river, or banning cruise ships.
While true we did that years ago and the other side is simply ignoring it.
Worse, the people we sold the idea too are stuck on it: they're convinced the solution must and totally be the performance, not the result.
I agree with you that consumer-level personal responsibility is absolutely not the way to go. To a certain extent I try to non-dogmatically "do the right thing", but I know it's simply a cute hobby.
The only solution is systemic. The incentives need to be in order for businesses and consumers to do the right thing not because it is the right thing, but because it's cheaper or more convenient. That can only be implemented via legislation and investment of public resources, hence from the political level.
And what determines whether the politicians in charge are ones who will implement the changes needed to mitigate the problem, rather than ones who will keep alive the system which is intensifying it? Well, we're back to square one: each and every one of us contributes to its intensification or mitigation through our decisions.
Moving from fossil is less convenient, not more. So, we're stuck.
And yet, we're not completely stuck. It is absolutely clear that not enough has been done to reduce our carbon emissions, and we're on a bad path on track to ~2.5°C warming in the next century. However, something has been done, and if nothing had been done we could easily be on track to >4°C global warming. That would be much worse.
So, how did we achieve what little we have? Well, because many people have cared, and have made the right decisions. Not enough people, or maybe not good-enough decisions, but some people, and somewhat good decisions.
So, what were the decisions which brought us down from an apocalyptic +4°C to a very bad 2.5°C path? Was it enough consumers making environmentally conscious choices, even if they were less convenient or more expensive. No. It was enough voters wanting their leaders to do something, even if it wasn't quite enough, but it was something. And something isn't nothing.
We will never have enough people voting with their wallet to fight climate change, because our rational understanding of the big-picture cannot overpower our intuitive day-to-day choices. However, we may have enough people voting with their ballot to fight climate change, because the rational big-picture can, sometimes, decide whom we vote for.
are you sure we aren't on the >4°C path?
AI could very well put us back on it.
Considering that current energy usage of AI is very likely to plummet in the coming years due to efficiency gains (which we've seem massive improvements on in the last couple years) and most of these large companies building datacenters are looking for and investing in specifically clean energy sources (nuclear) I don't think AI is a meaningful contributor compared to all the other high causes of global emissions.
Jevon's Paradox would like a word
AI which helps us design a commerciallizable fusion reactor might buy us a century.
I don't expect fusion to make a difference in either direction.
For big reactors: At current aluminium prices, the bill of materials for a global power grid with 1 Ω resistance the long way round is only about 10x the cost ITER (the organisation) expects ITER (the reactor) to be. Plug in your own numbers for target resistance as desired, halve resistance needs double the material.
With such a grid, you can put the PV in Angola and still get useful output in mid-winter nighttime in Anchorage.
For potential small reactors like Helion's "shipping container" target size, I won't say it can't work (I don't know enough to be confident), but I will say that we immediately find we have bigger problems because any hostile actor can simply choose to run them in neutron-source mode and turn everyday cheap depleted uranium* into weaponizable plutonium.
* I note that eBay still clearly has a dictionary merge on all nouns, given my search results came up with this:
Get the best deals for Depleted Uranium Metal at eBay.com. We have a great online selection at the lowest prices with Fast & Free shipping on many items!
Completely agree with the outlook ("fusion power irrelevant for climate change in every realistic scenario").
But where did you take those grid cost numbers from? Iter costs are <100bn AFAIC; and Germany alone (!!) projects more than that (top end) for grid expansion/operation within 2040 (mainly north/south and offshore connectivity).
Putting this note first, because it's probably the main point of confusion/surprise: I did say "bill of materials"; the estimated full cost for European and US grid upgrades that we need anyway for other reasons, with far less material, is order-of a trillion or so for US, half a trillion for EU.
For the material cost, just applied maths. By sheer coincidence, 1Ω of aluminium around the world is very close to 1m^2 cross section: https://www.wolframalpha.com/input?i=40000km+*+resistance+al...
This is almost exactly 1e8 (100 million) tons: https://www.wolframalpha.com/input?i=40000km+*+1m%5E2+*+dens...
This is $223bn at current prices: https://www.wolframalpha.com/input?i=40000km+*+1m%5E2+*+dens...
For scale, this is about what China makes in 2 years; if this is rolled out over 30, which would be optimistic but plausible, it's within the realm of just how much China increased production between 2023 and 2025, being spent every year.
To get to 10x ITER's own estimate for ITER, the wikipedia page says the organisation estimates the reactor will cost about €18-22bn: https://en.wikipedia.org/wiki/ITER
There are a lot of reasons not to do this as a single big 1m^2 "wire", amongst them being that the surface magnetic field is strong enough to be dangerous to approach with ferrous materials.
The "square meter of aluminium" is an interesting take. Not sure how much power you'd get over that thing; extrapolating from existing HVDC systems (Inga-Shaba is 1GW over 2x520mm²), I'd expect around 1TW, so twice the US demand?
But because Nimbys have no appreciation for beautiful pylons, projects in that direction are doomed for now anyway and everything needs to be buried underground at extra cost :(
Losses are I^2 R, which has the annoying consequence that % loss depends on how much juice you put through it, it isn't a constant percentage.
Pylons… eh. Doing this realistically rather than my napkin-maths, it would be a mix of many different solutions in different parts of the world, from competing environmental issues. Some would be pylons, some underground cables. Is the Sahara dry enough to run it on the ground, or in a concrete trench? I have no idea.
As a side note, every so often I keep being surprised on here by Americans who can't rely on the grid in winter because snow disables it, and some Californian forest fires are attributed to unmaintained pylons failing, dropping live wires onto the forest where they spark and light up the dry wood. These could both be resolved by burying more cables. Likewise within urban areas: here in Europe it's rather rare to see overhead lines in urban or suburban areas, unless they're over a tram/railway line.
IMO the real killer of any project like this, is geopolitics, not local politics. EU doesn't trust China, the US, or Russia; the current US administration doesn't trust or doesn't like basically everyone; Russia kinda gets along with China but few else; China would like to sell stuff to everyone but also have border disputes and other friction with many of their neighbours.
Properly disposing of industrial pollutants is less convenient than dumping them into the surrounding air or the nearby river.
For how long though? Solar and wind are very competitive now, electric cars have been good enough to transition to for over a decade, other industries can be decarbonized with the right incentives and enough investment. It's not like there aren't any ideas for how to farm or produce steel cleanly. And nuclear reactors can be made safer and cheaper now.
Seems more like a lack of political will with powerful lobbying interests opposing it and misleading the public. Fossil fuel companies could have listened to their scientists in the 1970s and changed their business models for a transition to cleaner tech a lot sooner.
For a long time to come. The energy density of fossil fuels is very high (about 50x higher than that of lithium ion batteries), there's a ton of infrastructure for handling and transporting them and a ton of infrastructure for using them.
They get turned into plastics and energy, two things which civilization feeds on voraciously.
It's not just inertia that keeps them going.
> The energy density of fossil fuels is very high (about 50x higher than that of lithium ion batteries)
That doesn't make sense. Batteries are an energy container, they're not energy itself. How can it be compared to a fuel? The direct counterpart to oil or coal is wind or solar radiation itself, batteries are used to amortize the supply and store an excess for emergency use, but otherwise those types of energy just immediately go into powering the grid.
The economic case for renewable power is actually extremely good, because unlike fossil fuels, they're effectively infinite and don't need complex infrastructure to extract. They're free. You only need a power plant that directly converts them into power. If we were just able to shift fossil fuel demand towards producing goods like plastics, this would already be massive. However, a lot of powerful people are deeply invested into fossil fuels and will do anything to tip the scales into their favor, despite gradually losing in the energy sector.
It makes perfect sense to look at energy + container subsystems.
It doesn't make sense to look at that in a vacuum. Energy transport over wire via electricity is much "denser" than transport via liquid or gas.
"It depends" is the correct answer, but the equation is shifting quickly towards solar + electricity.
You're the one looking at it in a vacuum. Engineering is all about looking at it in context and the main context where density of energy is important is in vehicles of all shapes and sizes. That's where the rubber quite literally meets the road. You can then theorize about what the 'weight' of the electrical energy is but it is pointless: the weight of container dwarfs the weight of the energy carriers (effectively the electrons) themselves. In the case of fossil fuels the ratio is more balanced, the container will weigh a couple of kilos and the fuel will way a bit more (say 10:1 or 20:1). So to compare the one with the other we weigh the batteries and ignore the electrons and we then compare that with the fuel because that is the dominant factor.
Solar + electricity are not directly suitable for powering electric vehicles, that's where the batteries come in.
Comparing apples (transport of electricity via wires) with oranges (transport of energy via liquid or gas) misses the elephant in the room: you are not going to be able to use those electrons without a suitable temporary storage medium unless you plan on carrying a very long and impractical extension cord behind your now very light EV.
This discussion is not solely focused on EVs.
The moment someone mentions energy density you can bet they are talking about vehicles and not about stationary stuff.
That is just retconning the discussion, please go back and check.
Why? In the context of the electrical grid, has the amount of storage you can have in the backburner ever been a choke point? If anything, fossil fuel power plants have the very same batteries to buffer some energy. But for the vast majority of power consumers that can just exist on the grid, power storage is nearly irrelevant because it can go directly from producer to consumer. Even in places where storage is relevant (anything that can't be tethered to the grid, like vehicles) the equation is different because the infrastructure you need to convert fuel to power (engines vs electric motors) don't weigh the same. Yes, even with that, pure electricity still falls behind somewhat, but it's getting better. And I was mainly talking about the power grid anyway, with how universal and important it is. Fossil fuel straight up loses in that sector, like what I said before, so replacing it is an easy choice... and yet we don't do that.
The only context in which comparing power densities makes any sense is the vehicular one.
It's an immense uphill struggle if you tried to get people to adjust to where transport is less available, and encourage living or working at closer ranges or conversely long range shipping/travel/vacations seen as more of a luxury. Just thinking about it I'm reminded of the outrage that was fabricated/stirred up over "15 minute cities" in the UK where the idea that you'd be able to get to most things you need day-to-day in a 15 minute walk was warped into a scare of state checkpoints, fines and surveillance. Or the retreat from working from home.
It's a huge adjustment from how the past few decades have established expectations, and it'll take a big force to change quickly, similar to covid even though that was short term in hindsight.
Really? Wind and solar are cheaper. Electric cars and motorcycles are more fun to drive.
Fossil fuels are profitable for a small group of powerful people, and they spend vast amounts of money to spread falsehoods.
While arguments can be made at the futility of individual action against a system action, it’s not like companies are making a bunch of product just to throw them in the trash. There are consumers of what is being produced!
Society’s choices and lifestyles are the cause of fossil fuel consumption, at a very high level. The plastic bag exists because it has users.
There are quantitative arguments against many silly consumer-focused initiatives. In aggregate tho companies aren’t burning fossil fuels for fun. Burning fossil fuels costs money, and a lot of people would rather not spend that money!!
> it’s not like companies are making a bunch of product just to throw them in the trash
Sure they do. You even mention one in the venerable plastic bag. Is it the best bag? No, of course not. Is it a good bag? Absolutely not. Is it the cheapest bag to produce? You betcha.
Consumers are often presented the least expensive option with the worst outcomes. See: https://en.wikipedia.org/wiki/Boots_theory
> Is it the best bag? No, of course not. Is it a good bag? Absolutely not
Plastic is absolutely the best packaging material ever created, it's so good, it feels like magic. It's light, it's cheap, it's waterproof, it's durable and doesn't just decompose, it comes in a miriad shapes and forms and so on. There is a reason it's everywhere
> it's cheap, it's waterproof, it's durable
One of those adjectives describes the plastic bag I'm familiar with. Sometimes it lasts long enough to get the food in the house without spilling through a hole which spontaneously appeared in the bag.
I remember when that switch at grocers from paper to plastic was taking hold, and you could choose. "Paper or plastic?" was the question asked. Some comedian (probably) had a good one liner: "That'll be 42.39. Kill a tree or choke a fish?"
It's mostly a good example of why comedians aren't a source of information.
Plantation lumber is a very sustainable industry, and plastic's environmental impact is highly context dependent.
The plastic bag is sold to businesses! If every supermarket in the world decided to never buy another plastic bag then they would no longer be produced!
There can be a futility to it all in that the “ideal option” simply isn’t produced of course.
I find boots theory is often a bit too convenient in this topic though. There is unlikely to be magic structural solutions that allow every part of your life to remain as convenient. At one point our lives will have to change in structure.
EDIT: to be extra clear, I think systemic coordinated changes is needed. I just think the “it’s the corporations doing this!” narrative to obscure the needs for reorganization of daily life on top of systemic change
Why don't you pay for a more expensive bag and bring it to the store?
Many cities have banned plastic bags, and the results have been miraculous for waterways and wetlands. It turns out that shore animals don't benefit as much from "hope a few customers choose the better thing, but otherwise let them take home single-use crap that immediately blows off into natural settings."
https://www.nytimes.com/2025/06/19/climate/plastic-bag-bans-...
Why do you assume I don't? Opinionated defaults matter, as that's what most users will end up using.
Would you be ok if stores offered the option between a cheap plastic bag and a more expensive non-plastic one? (All the stores here already do it, btw).
I think the externalities of plastic recycling must be internalized economically by requiring all manufacturers of items to pre-pay for the recycling of said items up front, as part of the manufacturing cost. Similar to how bottle returns are managed, which has been very successful. Items which are provably biodegradable or designed to facilitate repair may be exempt.
That ain't working. A plastic bag discarded in a ditch by the side of the road, or blown by the wind from the landfill, is still going to end up into the ocean. No amount of prepay recycling is going to take back that plastic from the ocean.
Plastic bags are already taxed where I live. Consumers pay that tax, obviously. Other costs imposed on producers of plastic items will just be passed down to consumers.
That's lovely, but it's not what I described. Bottles aren't just taxed. They have a refundable deposit. This ensures they don't end up in a landfill.
Exactly. The point of this sort of tax should not be to collect revenue, it should be to ensure that non-biodegradable bags are being disposed of correctly. To the extent that this is not happening, any bag tax is malfunctioning. Such a tax is either insufficient or poorly-designed. (Our city just banned chain stores from giving out plastic bags under 4 mils thick, and stores now give out paper and sell re-usable bags.)
Hard disagree on this.
Even if that state is just straight up burning all the tax income from single-use plastic bags, by taxing them you incentivize consumers and distributors towards untaxed, ideally more sustainable alternatives, like single use paper bags or robust multi-use bags.
> Our city just banned chain stores from giving out plastic bags under 4 mils thick, and stores now give out paper and sell re-usable bags
I don't see how this is not a massive win? Paper bags are significantly more sustainable, and multi-use bags are more durable and thrown aways less simply from being more expensive alone.
People are much more wasteful with things they didn't pay for, regardless of "inherent" value.
We’re not disagreeing. I’m saying that the tax should be set high enough that it creates the desired behavior, which is to disincentivize the widespread use of polluting plastic bags AND/OR ensure that they’re recycled and don’t wind up in the environment. If you’re charging $.05 per bag and people are just eating the tax and the bags are winding up in wetlands in similar amounts, that means your tax regime isn’t effective. You should either increase the tax or improve the system. My city’s absolute ban is equivalent to setting the tax to infinity, which is one solution that seems to work well.
> Society’s choices and lifestyles are the cause of fossil fuel consumption, at a very high level. The plastic bag exists because it has users.
Society's choices and lifestyles don't exist in some rational-individualistic vacuum. Companies advertise products while hiding known risks and side effects of what they're pushing. Cigarettes. Oil. PFOA/PFAS.
They all knew, and they did and continue to do it anyway. Regulatory capture solved all their problems by removing accountability.
This presupposes that consumers have infinite capacity to ingest the minute details of every single product they come into contact with.
Yes, the plastic bag has users. Do you really expect every single shopper to investigate how the bag at <grocery co> was made and if the plastic is recycled? What if they also have to do the same for every single thing they interact with every single day?
It's much easier to ask the people that work with the minutia of plastic bags every day, namely the people who make them, to maybe fix this problem.
Let us not pretend that the billions and billions spent on advertising by corporations leveraging deep knowledge of human behavior means the lion's share of blame goes to the victims of said advertising behmoth.
I never understood this. The companies sold you fossil fuel, you burnt it and got benefits out of it: transportation, energy, heating, constructions, fertilizers and food, etc. You want them to pay for the negative consequences of your fossil fuel consumption while you keep all the generated benefits?
> You want them to pay for the negative consequences of your fossil fuel consumption
No I want them to pay for the negative consequences of the lies they spread. I paid them for fuel, and I got fuel. I did not think I was paying for lies and I never wanted them.
https://en.wikipedia.org/wiki/ExxonMobil_climate_change_deni...
Where does the chain end? I burn diesel in my tractor to harvest corn. Should the feedlot that buys my corn pay for the tractor’s emissions? Should the slaughterhouse that processes the cattle pay? Should the supermarket that stocks the beef pay? Should the family who grills the steak on Sunday pay? Or just the one who eats the largest portion?
You either tax the fuel and pass the cost down to the consumers, or decide as a society to share the cost of the externalities and use general taxation for that.
Here, in the first scenario it directly punishes consumers for consuming more. In the second, it punishes everyone equally on everyone's consumption, which is unlikely to lead to behavior change. So yes, we should tax fossil fuels much more.
However, the first scenario will pass the increased cost of fuel down to the consumers affecting poorer people disproportionately. Example: some good that is produced with fossil fuels (including food) will become too expensive for low-income people, while richer (and more polluting) people will not feel the difference that much.
If you go for general taxation, you distribute the cost proportionally to income, making rich people pay more. Probably the ideal is a mix of both.
Ideally in the first scenario where we have well-functioning government, necessities like food and low-income housing would be well subsidized. Other things like random junk from Temu and large gas-guzzling trucks will be less accessible to poorer people by design.
Why should all of society pay for these externalities? If some people manage to improve their energy supply and don't require dirty fuels, why should they be forced to subsidize those who won't?
Taxing the carbon at the source is simply correctly pricing it, and because it makes it impossible to shift the externalities away from the producer it fixes the accounting problem that falsely makes fossil fuels appear cheap.
So… it’s like you completely understand the issue :)
And obviously, you tax the fuel at the source, right when it comes out of the ground. Higher prices get passed down, changing behavior because the products externalities are priced correctly from the start.
To be clear, the source would still be the consumer. Hydrocarbons can be used for non-CO2 emitting purposes such as chemical feedstock for pharmaceuticals, solvents, etc. We should only be levying a tax upon uses that emit CO2 into the atmosphere, i.e. burning them in your ICE vehicle. It’s not the fracking company that’s emitting the CO2 (unless they’re gas flaring or similarly emitting carbon during extraction but this is a rounding error on total emissions).
Right, because processing oil for non fuel products takes 0 energy, and produces 0 emissions, right?
You can. Everything- including basic things like food, transportation, construction, healthcare- will become more expensive, of course. My objection was to ask fossil fuel companies to pay after you already bought and burned your fuel cheap.
I want the emitter to be taxed however much it would cost the market to put the carbon back.
Obviously in such a system there wouldn’t be any fossil fuel companies so it’s a moot point.
But this isn’t purely economic. Fossil fuel companies are paying top dollar to ensure we destroy the climate. Just look at all the batshit propaganda around climate change. People genuinely believe it’s not a problem. It’s wild how effective the fossil fuel industry has been in convincing people the sky isn’t falling
Pretty sure those poor multi billion companies also got huge subsidies.
No, what we wanted for decades is for cars to shift to the free market of electric energy, just like every one of our other appliances have for decades. Electricity is a free market - can be generated by hydro, solar, wind, geothermal, even nuclear. If tomorrow they invent clean fusion power then electric cars would be able to benefit.
The cars being locked into fossil fuels is the result of fossil fuel subsidies from the government. Otherwise, OPEC raising prices would have long ago led to improvements in battery technology and electric cars. But the federal government shields the fossil fuels companies to make sure the “price at the pump” is small.
https://www.youtube.com/watch?v=vRnUY6V2Knk
We should be raising pigovian taxes on fossil fuels at the point of extraction, and redistribute it to all our citizens as a UBI. Alaska has been doing this for decades and they have almost the lowest GINI index of all states year after year.
Just like we want bottling and clothing companies to shift from plastics to bidegradeable materials. But you like to keep individuals distracted and blame them for using a straw and a bag, as if THAT is the main cause of pollution. And plastic recycling was a total scam designed to keep people distracted from forcing change on corporations pollution and unsustainable practices upstream.
Neat, I’ve never seen a fossil fuel company exec on hacker news before. Welcome!
I'm an environmentalist and I agree with this framing. The solution is going to be painful and must increase prices on products and services that fossil fuels are currently the cheapest solution for. If you're not willing to personally sacrifice anything to reduce fossil fuel consumption you can see why carbon taxes are not popular, right? France's protests against them, for example, are a good example of a populist reaction against attempts to regulate the economy to have less emissions.
The amount of fossil fuels that a working class individual burns are a rounding error compared to what big companies burn. How many private jets are in the air right now? Even if you drive the most energy inefficient truck ever produced, run your home HVAC at max, and buy gasoline just to burn in your back yard, you will never measure up. It's like saying we need to dry the oceans, so you should stop peeing in it.
And who are the customers of big companies driving the demand? Regular people or other companies who also produce for those people.
> if you drive the most energy inefficient truck ever produced
Sorry, but how was that truck produced? Where did the energy to make it come from? How was your home built, where did the energy come from? Where did the materials come from? How did the workers come to the job? What did they eat, and what do you eat? Do you go to an office? How was it built? How do you and your colleagues get there? Do your children go to school? Do you go to hospitals when you're sick? Etc.
Its a case of prisoner's dilemma. Individuals making the proposed lifestyle changes in order to make a genuine dent in AGW amount to jumping on the tracks in order to stop a freight train.
This is the one issue where I feel some sympathy with the right. I hate "Virtue signaling" about as much as they do. I'm sorry, but if you are going to snap at people over eating beef, while you fly/drive all over the country/world unnecessarily, you are absolute full of shyte.
I am not a vegan. My social world in D.C./NYC has many secular, left-wing, vegans. Many of them are friends or loved ones. They demonstrably speak their mind in front of me on countless issues on which we disagree.
I have dined with them countless times at restaurants where they order vegan and I don't. I have never once been "snapped at" about my dietary decisions. Some of these people have dedicated years of their life to non-human animal rights activism.
So I am very skeptical that this shaming occurs at any appreciable scale. I suspect it is mostly psychological projection: one doubts the morality of one's decisions, judges oneself harshly, but experiences this as the judgement of others.
Thank you for articulating this so succinctly.
Don't forget buying mountains worth of crap that gets used for a month or less and trashed.

Right to Repair and some type of incentives that actually rewarded it would probably do more globally than most other consumer level solutions.
Prisoner's dilemma is a bad reference here.
Prisoner's dilemma is about situation when optimal outcome requires cooperation from all participants.
In the situation with climate change, personal decisions of 99% of Earth population do not really matter.
You are correct that this is not a prisoner's dilemma, it is a tragedy of the commons[0]. However, if a wizard could magically control the "personal decisions of 99% of Earth population" and make them optimal for reducing CO2 emissions then, believe me, climate change could be trivially solved.
It is a classic cooperation problem. Perhaps not prisoners dilemma. Perhaps not at individual scale. Probably tragedy of the commons.
Cooperation is not consuming fossil fuels. Defection is consuming fossil fuels.
If you cooperate and other defects you suffer climate impact and expensive energy (expensive everything, worse economic growth than others).
If you defect and other cooperates you suffer climate impact but at least you get cheap energy (cheap everything, more economic growth than others).
People, nations, corporations, etc don’t stop using fossil fuels because they incur a penalty against their competitors if they volunteer to and their competitors don’t.
The assumption here is that fossil fuels are actually cheaper. But an electric car pays back the higher upfront cost in fuel savings in significantly fewer miles than most cars will have put on them. Solar generates power at a lower cost per kWh than coal.
The fossil fuel industry has to be actively sustained through subsidies and government regulation hostile to alternatives. Maybe that wasn't true 50 years ago before the alternatives got viable and cheap, but if it's not true now then why did we stop subsidizing electric cars while we still subsidize oil companies?
WDYM personal decisions don't matter? Industrial and agricultural sectors, which both in sum contribute 50% of total greenhouse gas emissions, produce what is in demand from consumers. Another 15% of emissions is from personal vehicles. Changing personal habits is the only way we can ever reach some utopian climate targets. Utopian because old habits die hard.
Once again, personal decisions on the consumer side doesn't matter here. Unless all consumers cooperate to force a ban on practices that are bad for environment. However that basically means forcing specific decisions on the 1% that control laws and business.
If consumers stop buying gas guzzlers, the impact of personal transportation on the climate will reduce. Are you suggesting the 1% controls the minds of the 99% to do things that are harmful to the environment? Past some point, there is at least some level of personal responsibility?
Several car companies had plans to stop making ICE cars at some point in the near future. Everyone stopped buying their cars and they have had to backtrack (e.g. Porsche). We have all collectively decided that environmentalism is hot air (tee hee) and we'll just continue with business as usual.
Corporations do whatever is in their financial interest, provided it is legal. They're neither good or evil. (If they were DnD characters their alignment would be "lawful greedy".) What is legal is determined by governments, who are elected by individuals like you.
This is why people need to be reminded of the impact and causes of climate change. You can't just say, "Oil corporations are evil" and absolve yourself of responsibility. That's how nothing gets done. Corporations are not going to stop being "evil" of their own accord. They're going to obey the laws and regulations set forth by the governments they operate under.
Americans elected a president who openly campaigned on bringing back coal and said, "Drill baby drill!". Oil executives made campaign donations but, ultimately, this is the fault of Americans. They're not educated enough and they tolerate too much money in their politics. Scapegoating oil companies does nothing to solve these problems.
I hear what you're saying but also have lately felt a lot of frustration with this framing. I definitely agree that large corporations share an outsized portion of the blame; they have misled and misdirected us past the brink of crisis in pursuit of profit. And as you point out, one of the special cruelties of their system is that it prearranges individual consumer options so that we have the illusion of choice, but ultimately wind up complicit no matter what we choose. Thus its incumbent on us (collectively) to make a decision that's not on the menu we've been handed. But (critically) its still going to be individuals making that choice. It's not enough to merely topple Big Oil at a social scale, we will also have to give up our F-450s and sprawling SFH tracts with four car garages. It's not necessarily fair, and it's not necessarily our fault, but it's still our responsibility (because it's ultimately our future that's at risk).
It is still everyone's responsibility, just not to equal extent. That petrolstate also rose to power through democratic elections.
https://en.wikipedia.org/wiki/ExxonMobil_climate_change_deni... it also influenced those elections.
Mainly because petrolstate's money was considered free speech and allowed to speak louder than citizens when it comes to influencing representatives.
Problem is that we if we all stand in a circle and point fingers at the next guy who is to blame, that doesn't really move us toward any sort of solutions.
In fact the reason it's so easy to find others to blame is that the responsibility is a shared one. Holding consumers responsible doesn't absolve producers, or governments for their participation. All have to be held responsible for their actions. That's the only way forward.
> Problem is that we if we all stand in a circle and point fingers at the next guy who is to blame, that doesn't really move us toward any sort of solutions.
Because of the power of lobbyists and their war chests full of cash, even if we made that circle surrounding our congress critter so everyone was pointing at them, we'd still have no effect. Our shame circle would only be uncomfortable for a short time which would quickly be assuaged by the soothing feeling of another large donation from a lobbyist.
Most people would agree that drug dealers hold more moral responsibility for delivering a product that they know is highly addictive but on the other hand no one would absolve an addict of any responsibility. Even you think addiction is a illness, we still expect people to help themselves by deciding to get help/seek treatment to fight the addiction.
This sounds sensible in isolation, but the real analogy is that the drug dealers have spent billions of dollars convincing the general public that drugs are healthy and better than the alternative of sobriety.
And also, when I go to the store to buy my daily needs like food and soap, they’re all packaged in the drugs.
Oh and I have to consume the drugs to get to the store because there’s no safe way to get there on foot or on a bike, and there’s no bus or train service because someone at GM/Ford paid my representatives to not fund that.
Then when I take my used drugs to the drug recycling center, they don’t actually get recycled because it isn’t profitable. But my recycling agency tells me that all my drugs get reused.
Seriously, just watch a paper towel ad or something. They act like it’s impossible to clean up a spill with something reusable.
Enjoyed reading your comment but the fact that it's more environmental than it is biological (is it though ? Isn't comfort appreciation biological too ?) doesn't change the moral calculation of my analogy which imho still holds: Quitting drugs is hard but it needs the addict's involvement
It’s government’s fault for not regulating it properly. You can’t give individuals choice and then blame them. Just like you can’t give industry the ability to mass produce these things that are so inherently bad for current but especially future humans. Only governments are responsible for playing that kind of long game.
> It’s government’s fault for not regulating it properly.
Who is government responsible to and responsive to? Individuals.
> You can’t give individuals choice and then blame them.
That is exactly how the world and responsibility works. You have the choice to do right or wrong, and are responsible for the consequences - in Abrahamic religions, it goes back to Eden.
You personally have endless choices every day where you can do wrong with no penalty to you. Unless you are sociopathic, you generally do the right thing.
This was a tailored response to this context. You trying to apply it generally is quite ridiculous.
Governments exist so that individuals can function as a society. Your point is circular (Government<->Individual). Governments are responsible to a collection of individuals, a society. We enable our governments to oversee safety of toys, vehicles, toxic materials, etc. because it is quite inconvenient to make those evaluations at a individual level on a daily basis. We are also human who have short-term value systems, governments are supposed to force us to act with a longer-term outlook. Eg. caring about the next generation.
Every industry ever is going to externalize all the costs you allow it to externalize.
The individual responsibility is to vote for representatives that prevent such externalization through regulation, and to stand behind such regulation even if it is slightly inconvenient (plastic drinking straws) or somewhat costly (gas, flights).
The biggest problem is that a significant part of the global population is not willing to make even the smallest sacrifice in lifestyle towards such a goal (=> this is often difficult to see if you are in a more left/green bubble, but i absolutely true of the average citizen).
We, as voters, have expressed so little care for climate and environment sustainability that politicians don't even bother catering towards that niche any more.
In the US there was an super obvious choice 25 years ago in the US between genuine, ambitious sustainability and some generic politician not even half as competent as his father, and we all saw the outcome; politicians since barely even bother pretending to be concerned about climate sustainability because voters just don't care.
> consumer-level personal responsibility
Indeed, the biggest personal responsibility is to make this a top political priority when deciding who to elect. Nothing will change until we consistenly fire leaders who refuse to act decisively on this.
There is nothing g to “disagree” about. Of course systemic changes are required. But if the individual improve their actions it will have a meaningful impact too
Without systemic change the impact of individuals wont be meaningful. Maybe on a spiritual level but they won’t contribute meaningfully to the climate change (or non-change)
It won’t and believing it will is part of ensuring nothing changes. All energy you spend on personally changing should be instead spent lobbying, organizing, and otherwise working politically to effect systemic change. There is no value in individual change. It’s worse than doing nothing.
Americans use a lot of power. Buying big houses means they have higher heating and cooling costs. All this makes a big difference.
If you drive a fossil fuel vehicle, you have chosen to buy into this. If you drive it 3 blocks when you could walk, you've chosen to go the way the fuel company wants you to. That's you.
Plastic is a bit different, you didn't choose the packaging. And you probably don't have the option to recycle anyway. Putting in a special bin doesn't change the fact that it's probably going to a landfill anyway.
Some of it's consumer level. Do what you can. Don't whatabout it.
Plastic is a fantastic material, that's why it's chosen for the packaging. I also don't see the problem sending it to a landfill as long as it stays there.

I gave up driving in the 1990s because I knew back then the situation was untenable for the climate. I chose to try to live a life that contributes less to the destruction of life as we know it. Life without a car has brought sacrifice, but I'm glad I did it. No, my single sacrifice won't save the planet, because far too many people are addicted to cheap energy, and free movement. Blaming the oil industry is like blaming the cows because you ate too much cheese. Now there are electric cars, but unless you are charging it up every day from solar/battery (along with your house), then you're still only helping a little.
Suppose the fossil fuel lobby disappeared tomorrow, along with government subsidies and any hegemony you think exists - people are still going to be addicted to cheap energy. Only when the forms of energy they currently rely on really starts costing what it would cost to save the planet from climate change will you and others realize that every decision has a consequence. You want to drive 2+ hours in traffic every day? That has a real cost for the environment to do it with fossil fuel.
Maybe try changing your life so that you don't spend 2+ hours every day driving around in traffic. That's what I did, I got a job locally, got rid of my car, and started riding my bike everywhere. If it was far, I planned ahead take the bus/train. I do this in Los Angeles, since the 1990s - not exactly a bike-centric place to live, but it is entirely possible to do. Of course it's more difficult to do this in rural areas, but maybe that should be the exception.
It’s actually a lot more systematic than you think: https://magarshak.com/blog/government-and-industry-distract-...
Andrew Forrest, a well connected billionaire, puts the blame on a group of 1000 "captains of industry".
https://www.smh.com.au/environment/climate-change/inside-and...
I have to disagree here.
Companies would stop doing anything in the face of a unified boycott.
We love to blame companies, private equity, capitalism, government, anyone really. It's us. They lie to us because we want to be lied to.
It's another claim of powerlessness, which is exactly what the 'fossil energy industry' wants people to say - it's demoralizing, paralyzing, and like any disinformation it's a distraction from actually doing something; now we're debating this stuff instead of doing something. So is the victim debate - who is at fault, assessing blame, etc.
Nobody, as a single human being, can accomplish much in any field. Every significant thing humanity does happens in large groups. The good news is, we are hardwired to work in groups - you see it all over, all the time. People naturally organize and work together; think of FOSS projects, for example. And that is what democracy is, and democracy is the most dynamic, effective, changeable method of government in human history.
Let's stop wasting time debating it and get to work. A simple thing to do is to reduce personal climate output. Again, you can't have much effect alone, but humans act together, and we all can do our part. That's why there isn't trash covering the streets - one person can't prevent that, but everyone is putting their garbage in the bin.
I am responsible for the consequences of my actions and words, and for my community - we all are, of course. The victim / blame perspective is the opposite of that - victimhood is a justification / rationalization for a lack of responsibility, for inaction. As anyone with experience of decent management knows, that is the last thing you do. The problem needs to be solved.
The 2 biggest contributors to climate change are ...
- US Military
- Cargo Ships
You fix those 2 things and like 60% of pollution goes away.
Merchant shipping contributes around 3% to CO₂ emissions. That is smaller than, e.g., electricity and heat generation, road transportation, manufacturing, construction, and agriculture.
It’s funny that this is always ignored or downvoted when consumers are a relatively small part of the problem. Surely shaming people harder will fix the problem, this time.
If everyone chose to eat veggie burgers and seitan steaks instead of using beef, the climate's trajectory would immediately improve. For all the responsibility of industry, many individual world citizens could, and many have, changed their lifestyle due to the moral issue of climate-changing emissions.
The concern about climate is well placed. Ripple et al. lay out a serious case that we may be closer to tipping cascades than models predict, with the Greenland Ice Sheet potentially vulnerable to tipping below 2°C warming, well before 2050.
But "invest an equal share of the resources currently being pumped into AI into climate" misidentifies the bottleneck. Marine cloud brightening could produce meaningful planetary cooling for roughly $5 billion per year at scale (NAS estimate). That's like what? 1% of what was spent on AI infrastructure last year?
The money exists. What doesn't exist is the political coordination to spend it.
The goddamn Alameda city council shut down a University of Washington MCB field test in 2024 because nobody told them it was happening on their property. Go look it up.
This's the actual bottleneck: governance, coordination, and political will, not capital.
When someone says "we should invest resources in X instead of Y," it's worth asking who "we" is and what mechanism they're proposing. AI investment is private capital chasing returns. You can't redirect it to climate by wishing. The implicit model, that Society has a budget and we're choosing wrong, assumes a resource allocation authority that doesn't exist. If you want to argue for creating one, that's a real position, but it should be stated openly rather than hidden inside "it would be sensible."
Also ... "AI won't solve it; it only makes it worse" is doing a ton of work! The energy consumption concern has real merit. But materials science, grid optimization, and climate modeling are direct climate contributions happening now. Google has saved energy in its datacenters ... using AI!
Blanket dismissal of an entire domain of capability isn't seriousness, it's pattern matching. (Ironically, there's a phrase for systems that produce plausible-sounding output by matching patterns without engaging with underlying structure. We're told to be worried about them.)
> not capital
Capital, and by relation the system that centers the idea of Capital as a method for moving around resources is at the very center of this.
Since Capital follows near-term incentive, if the "pollute the world" path has a greater near-term incentive, that's where the market will follow. If a single member of the system goes for long-term incentive(not cooking the earth), other near-term incentive chasers will eat their lunch and remove a player.
The system itself is a tight feedback loop searching for local maxima, and the local max is often the most destructive. With chasing the local maxima, also comes profit and capital that influence the political system.
What you've done here is called a fully-general counterargument. You should be suspicious of these!
If capital inevitably follows destructive local maxima and defectors get eaten, then no coordination problem has ever been solved, right?
But we banned CFCs! We got lead out of gasoline! The Montreal Protocol exists and worked.
What you're describing is the default behavior of uncoordinated markets, not a physical law. The entire history of regulation and international treaties consists of mechanisms that override local incentive gradients. Sometimes they fail. Sometimes they work.
"The system itself is a tight feedback loop" treats the system as fixed rather than something humans have repeatedly modified. The question is whether we'll add the right feedback loops fast enough, not whether adding them is metaphysically impossible.
My original point stands: the bottleneck on MCB isn't that capital won't fund it. It's that the Alameda city council didn't know a field test was happening on their waterfront and NIMBY ... people ... made noise. Governance failure, not capitalism failure.
> But we banned CFCs! We got lead out of gasoline! The Montreal Protocol exists and worked.
None of these were done via capitalism, they were done in opposition to it.
And I know you weren't claiming they were, but the problem is all the power centers behind global capitalism have captured government (at least in the US) completely and are doing everything in their power to strip existing regulations and make sure the only new ones aren't in the name of the common good, but only to build moats for themselves.
It is great that we solved these problems in the past, but we are increasingly not doing that sort of thing at all anymore.
It's also worth distinguishing uncoordinated markets from ungoverned markets. Markets exhibit vast and sophisticated organic coordination without state prodding. I don't just mean to pick at this word "uncoordinated" but more deeply at the particular issue of near- or far-sightedness. Has it actually been established that organic economic coordination does worse at protecting "the future" than some particular alternatives?
The government is failing to control the problem because it got bought out by the capitalists who run the companies that continue to cause the damage. The law in the US explicitly allows this, though it's "decent" enough to hide it in a paper bag.
It's certainly a governance failure, but I'm not sure what the fix for it is, and I don't see how capitalism gets off scot-free.
People will have to vote for non-captured candidates (good luck finding them) or protest in large enough numbers that the system will change. Those people will also have to be critical thinkers to a degree that they can consciously push back against the wall of marketing and propaganda pumped out by those in power with money. And they will have to self educate since governments generally don't teach people these skills while they have them in school for 12 or more years. From my point of view the future looks pretty grim but I'm certainly hoping to be surprised or corrected!
> Marine cloud brightening could produce meaningful planetary cooling for roughly $5 billion per year at scale (NAS estimate).
Eh. Cloud brightening is a temporary hack, stops working as soon as you stop actively doing it, and isn't an alternative to switching away from fossil fuels. It's probably worth doing to push back the "ice melts and releases more carbon" thing but let's not confuse it with the extent of what needs to be done. You can't actually solve the problem for $5B/year.
> AI investment is private capital chasing returns.
Getting private capital to work for you is a good way to solve the problem. The real problem is politics.
The EV tax credits and the subsidies oil companies get were costing about the same amount of money, but we only got rid of one of them. Nuclear should cost less than fossil fuels, but we're told that fission is scary and Deepwater Horizon is nothing but spilled milk so the one with the much better environmental record has to be asymmetrically regulated into uncompetitiveness.
If we actually wanted to solve it we'd do the "carbon tax but 100% of the money gets sent back to the people as checks" thing, since then you're not screwing everyone because on average the check and the tax cancel out and corporations pay the tax too but only people get the check. Then everyone, but especially the heaviest users, would have the incentive to switch to alternative energy and more efficient vehicles etc., because everybody gets the same check but the people putting thousands of miles on non-hybrid panzers pay more in tax.
The "problem" is that it would actually work, which is highly objectionable to the oil industry and countries like Russia since it would cause their income to go away, hence politics.
Cooling the planet is neither a technical nor financial problem. The problem is that environmentalists want this to be a moral issue. They already decided on the solution. If the solution is not environmental communism with them in power, they will not have it.
>Cooling the planet is neither a technical nor financial problem
Yes it is. All solutions have trade offs.
Unfortunately, more people seems to care about getting AI to play SimCity than the environment.
Renewable energy technology is ready, right now today, to replace fossil fuels. All we have to do is start doing it, but the Oil lobby is just too strong apparently. There is no political will. I wish I was wrong, but I just don't see humanity pulling together to solve this one.
> Renewable energy technology is ready, right now today, to replace fossil fuels. All we have to do is start doing it, but the Oil lobby is just too strong apparently. There is no political will. I wish I was wrong, but I just don't see humanity pulling together to solve this one.
Sorry, but its really not. Perhaps in some sectors such as ground transportation, but definitely not in air and sea transport and fertilizer production, and many industrial processes. At least not at scale, where would have to make massive lifestyle sacrifices which are not politically acceptable outside of extreme authoritarian states who have no reason to do this anyway.
Solar is so cheap and getting cheaper than we can power those sectors with air-to-fuel plants. A carbon tax would go a long way towards leveling the playing field with carbon neutral or carbon negative alternatives to fossil fuels.
We are a planet of 8 billion people, interest will vary widely. Expecting everyone to swarm on the same issue at the same time is simply not how humanity has worked in the past. Innovation often happens because many people go different directions, testing what works and what doesn't. Getting AI to play SimCity may be a stepping stone to real life urban planning, or it may be nothing, who knows?
> Getting AI to play SimCity may be a stepping stone to real life urban planning
Urban planning of the SimCity sort isn't particularly difficult. The associated politics are the issue.
Hence the "or it may be nothing"...
Humanity in the past has acted to eradicate Polio through global vaccinations, fix the Y2K computer bug, allow the Ozone hole to repair by banning CFCs, form a United Nations to prevent WW3 among other things.
We are actively making noise about pulling out of groups like the UN/NATO.
We are actively undoing regulations to reduce pollutants while promoting "clean" coal.
We are actively undoing vaccinations policy.
We does not necessarily equal humanity at this time, but it sure feels like it if you are under the We administration.
That’s true. WTF happened to those competent people?
If you're looking to experience a "climate change" simulator, kind of, the game Oxygen Not Included is an interesting chemistry sandbox where you need to balance things like O2, heat, food, etc in a "terrarium" of sorts. The parallels to climate change are similar to real life--most of the game ending problems you encounter are from short sighted thinking earlier on/kicking the can down the road.
If you're near Lake Powell, you could also visit it right now and compare it to what you remember. Not a simulator, just a pretty scary real thing.
Gotta love the cycle 200 heat death
I found Half-Earth Socialism: The Game[1] to be fun for quite a few playthroughs.
> And, no, AI won't solve it; unfortunately, it only makes it worse.
A conclusive argument for this still seems out of reach. AI does solve some problems, and it's not exactly clear which problems AI "only makes worse". It's not clear how much energy all of our AI systems will use, and while it's tempting to outright believe they'll simply use more and more, even that's not yet clear based on arguments presented.
> It's not clear how much energy all of our AI systems will use, and while it's tempting to outright believe they'll simply use more and more, even that's not yet clear based on arguments presented.
For the last 20 years, power consumption of HPC is increased per cubic inch as systems are miniaturized and density increased. The computing capacity increased more than the power use, but this doesn't mean we didn't invent more inefficient ways to undo significant part of that improvement.
It's same for AI. Cards like Groq and inference oriented hardware doesn't consume as power as training oriented cards, but this doesn't mean total power use will reduce. On the contrary. It'll increase exponentially. Considering AI companies doesn't care about efficiency yet means we're wasting tons of energy, too.
I'll not enter into the water consumption debacle, because open-loop systems waste enormous amounts of water.
All in all, we're wasting a lot of water and energy which would sustain large cities and large number of people.
with regards from your friendly HPC admin.
Outside AI independently uncovering some energy breakthrough there is nothing it can do to help, only hurt. We already have a source of clean, cheap, unlimited energy, we aren't rolling it out the way we could and should because some rich people would rather have us on a subscription plan where we literally light our source of energy on fire so we have to keep coming back for more.
AI has already pushed fusion research forward.
We could certainly do better but switching isn't as simple as you imply. You also conveniently left out the part where activists historically blocked nuclear buildout.
> It's not clear how much energy all of our AI systems will use
Is it superior to zero?
Does AI replace existing, more costly energy use patterns to the extent that its own energy use is offset?
Perhaps someday. For now, it amount of energy used to produce and run these models is astronomical. It may be the case AI is a net positive for the environment at some point, but as it stands that is nothing but speculation. The reality is it is making the situation worse.
The major road blocks for solutions has been unchanged for the last decades. The same strategy talked about at the beginning of the 21st century still has the same problems, and while more people are aware of climate change, we are only further away from creating and implementing solutions.
Taking Europe as an example, the main strategy is still to use the combination of natural gas, biofuels created from farming corn, and renewables to enable electrification. This strategy lacks both scientific and political consensus among the people who believe in climate change. The result is that as strong one side of the same movement are pushing for it, the other side is also pushing against it. We see the exact same thing with the other major strategies involving tree planting and changes to the culture (diet).
It's important to remember that in REALISTIC worse case emissions projections, by 2050 - we will have CO2 higher than levels seen in the last 10 million years - but there was a 500 million year period where CO2 levels were an order of magnitude higher than that - and there's NO WAY we're getting there without destroying civilization first, so there's no chance on current trajectories that we turn the planet into Venus.
The super danger zone is ~1000 PPM CO2 - where ocean chemistry changes. In worst case scenarios in 50-60 years, we could get there - but there's a lot of reason to believe we won't, and we DEFINITELY aren't getting there by 2050.
The graph the main source shows is cherry-picked. Look at this: https://co2coalition.org/facts/for-most-of-earths-history-it...
Saying we're on a "hothouse" trajectory plays into the Apocalypse / Earth Becomes Venus trope, which is so ridiculous for our lifetime even under the absolute worst case realistic scenarios.
I agree to an extent that each of us contributes in a manner, but the manner that we contribute is not certain. A person who puts more effort into reducing their own personal climate impact could be doing worse than using the same effort to enact systemic change. It could be bailing water on a sinking ship instead of fixing the leak. The problem is you might not appear to be doing anything in isolation. Just spending that extra effort at work and sending the money earned to the ship patching people so they can get what they need would fix the problem better. If you choose bailing are you not just choosing something visible but ineffective over achieving the desired outcome but just being a boring taxpayer.
As for AI, to characterise it as a "solution to problems we didn't really have" is placing your opinion over others. They may be right or wrong about it but many AI proponents firmly believe that AI can provide solutions to real world problems that we definitely have. You may disagree about their potential effectiveness, and that's ok, but at least tolerate that people might have different ideas about how to make the world better.
Framing man made climate change - aka the 6th mass extinction event - as a problem in search of a solution is by itself the very reason we won't "solve" it.
Trying to solve climate change in anything but a very narrow sense is like trying to perform humane torturing. One can either treat others humanely _or_ torture them. The two at the same time is impossible. The majority of conversations around climate change focus on doing the same things - modernity - but without the negative effects. Chasing a way to humanely torture children will not in fact stop the torturing of children. The goal is wrong! No amount of "solutions" will help you if they all aim to achieve the goal that itself is the root cause of the issues.
> [...] every one of us contributes to its intensification or mitigation through our decisions.
I would like to note that the decisions we make at our jobs have the most impact.
We contribute to it 1% by the actions we take as individuals, and 99% by the leaders we select.
Maybe we could ask AI!
https://chatgpt.com/share/698ce97b-4d54-8000-aecb-542ceecb00...
The difference is emblematic of the difficulty in getting attention for climate mitigation. AI succeeds because you can sell a service to an individual human which will give them advantages over other humans. Climate change mitigation fails because you are trying to sell a service to humanity which will result in a better end state over some other hypothetical imagined future. Humans make decisions, not humanity, and many of them are pretty bad with both hypotheticals and imagination. It's no wonder that a product designed to make them do better at what they do, right now is more successful than one designed to make everybody do better than what would otherwise have resulted, 50-100 years in the future when they'll likely be dead.
Any kind of workable solution to large, societal-level problems needs to deal with the principal agent issue. Society doesn't actually exist; humanity doesn't actually exist. These are abstractions we use to label the behavior of individual people. You need to operate on the level of individual people to get any sort of outcome.
(FWIW, this is a major reason why concepts like markets, capitalism, democracy, rule of law, and federalism have been successful. They work by aligning incentives so that when one person takes an action that is good for themselves, they more-or-less end up benefitting the people around them too.)
Unfortunately it won't happen, as humanity rather nuke ourselves generating memes, while driving beverage from paper straws.
> that each and every one of us contributes to its intensification or mitigation through our decisions
I‘ve travelled quite a bit and I find it hard to convince myself that I as a city dweller contribute any meaningful amount to pollution or waste. I‘ve seen rivers of trash flow directly into the ocean. The rich and wealthy pollute disproportionally in such a way that I don‘t think offloading the responsibility to the general public is fair.
The simple counterargument is that there many more of us than there are of them, so even if on an individual level we have less effect collectively we have much more.
> It is important to keep reminding ourselves that climate change is a real problem for humanity and that each and every one of us contributes to its intensification or mitigation through our decisions.
Which decisions though? The decisions to hold back nuclear, NIMBY solar, or keep cheap Chinese EVs out of the hands of consumers have a much bigger impact than whether you leave the lights on. Freezing in place with our existing fossil fuel system and fearfully minimizing our consumption will at best only slightly slow our decline.
IMHO, we must rise above fearful, superstitious individual moralism and boldly apply ambitious zero carbon energy science, engineering and policy, including fission (to keep things going in dark winters) and possibly even geoengineering (pending extensive research and small-scale pilots).
We cannot afford continued reflexive, neurotic rejection of any deviation from the status quo as we approach these tipping points. Continuing exactly as we are is not safe, nor can we return to preindustrial society. We need to build zero carbon supply for the needs of civilization. Including the stuff that people are uncomfortable with out of ignorance.
We need a plan. Neurotic criticism of every realistic plan is not a plan.
We cannot afford a continued overhang of 1970s Boomer environmentalist sentimentalism. Scientific engineering of the future is needed, not ideological nostalgia for an idyllic past we can no longer return to.
AI may not do much good directly, but it has the salutary effect of making rich tech companies care about electrical supply and distribution, accelerating the learning curve towards cheap supply.
> each and every one of us contributes to its intensification or mitigation through our decisions.
How on earth would anyone contribute to its mitigation? Of course everyone, everyone, contributes to its intensification, no matter how "green" they are. Yes of course, people contribute to the intensification in wildly different degrees.
As a human living on this planet, with roughly another 50 years left, I say we allow our actions to continue. We are unable to stop those in power and with high influence from doing anything; we deserve what is coming. Earth will be fine without us. Good luck everyone!
I think if the hope is that the whole world comes together to reduce emissions to a meaningful level, there is little to no chance of that. Even in the face of clear evidence, many leaders either do not believe it or do not think it will affect them in their lifetime. Capitalism and globalization march to a different drum.
The hope becomes that we can innovate our way out of the problem with technology, that is the race to the finish. AI will likely help us get there faster, but 2nd place will not be an option.
You could say industrialization was a solution to a problem we didn't have...but efficiency and profit is always the pursuit of business, and unfortunately that is a lot of the world we live in.
And I say this as someone who loves the idea of energy that doesn't come from burning things.
Imagine if we had laws that required all LLM compute to come from solar, or other sustainable power sources. We could have used the market's thirst for AI as a backchannel way to force creation of new sustainable energy.
In contrast to Elon/XAI's illegal methane fuled datacenter in memphis
Imagine if we had people that actually listened to scientists, reduced their carbon footprint and changed their habits.
every year (month?) that passes people are saying the end of the world is right around the corner due to climate change. then 10 yrs passes, nothing happens, and they keep saying the same stuff.
the system warning you the world is in big trouble dont remind you 'their side' has been saying the sky is falling for ~40+ yrs.

I've started composting. I'm sure that'll outweigh the average Vegas visitor's emissions. /s
I'm being a bit facetious obviously, but it does feel a bit like tilting against windmills. We need policy and systemic changes, if we're relying on individuals to all collectively start doing the "right thing", we're sunk.
I agree. But at least in a democratic system, the "each and everyone of us" are politicians that each and everyone elects. So it starts from the basis, IMHO.
You laugh but if everyone changed just some of their behavior, we would be in a much better place.
We used to reuse glass jars, now it’s plastic. We used to can goods, now it’s plastic. We used to use refillable bottles, now it’s plastic. We used to have car doors that went “thunk” when you slammed them shut, now it’s plastic.
If we each are mindful of the amount of trash/litter/waste we produce and take an active step towards minimizing it, we would all be in a better place.
> You laugh but if everyone changed just some of their behavior, we would be in a much better place.
Please be more specific about "some" and "much" because I don't think that's true.
As far as climate goes, turning oil into single use plastic has very little effect. We could cut plastic use 90% and nothing would really change.
The problem is that a single consumer can't throw themselves into the gears of the industrial machine to slow its progress. If you stop buying food in plastic containers, the food will still be produced, and it will still be purchased by the large multinational corporations that have supply contracts with the food industry, it will just go straight into a landfill when its expiration date passes instead of being purchased. Unsold subsidized produce, which took petroleum based fertilizers to grow, and petroleum powered equipment to cultivate and distribute, will rot in a landfill. Farmers won't stop growing it if you stop buying it. The damage has already been done by the time you make the choice to purchase it or not, and it takes more than a handful of people making a conscientious decision to reduce waste to stop the waste from happening in the first place. And that's if you even have a choice in the first place. The only way to eliminate carbon emissions is to return to manual labor and subsistence farming, and since all the arable acreage is owned by land barons and the price is so high, even that is out of reach of the average consumer. We are trapped.
If you buy an electric car, consider the amount of petroleum it took to forge the steel, power the aluminum smelters, and ship the components around the world on titanic ships. How long does it take to pay off the carbon debt that was incurred by getting rid of that old polluting car? How much petroleum would it take to relocate to a locality with clean-energy powered public transit? What other externalities are incurred by such a choice, and are they greater than simply maintaining the status quo? Is it even within the means of the majority to make such a choice?
Consider that aviation is a much larger contributor to emissions. Airlines will consistently fly completely empty planes just so they can maintain a parking spot at a given airport. Or compare the carbon emissions of the military to the rest of society. Or the quantity of flare gas that gets uselessly burned off by oil rigs. All market forces which a single consumer or group of consumers is powerless to stop. And all of which are backed by investors with more clout to sway the powers that be than you or I will ever have.
As a sibling commenter said, it's a fun hobby and makes us feel a little better about ourselves, but it's a drop in the bucket. A depressing state of affairs to be sure.
I get what you're saying. I lived on a sailboat with solar so I understand... The sailboat I lived on was made with fiberglass, a petrochemical product. We would still be in a better place though even if the inevitable demise will still occur. It would just occur later.
We used to live lifestyles that didn't require driving every day and flying eight times a year...
the great thing about these sorts of personal choices is that you can make them for yourself without having to be afraid of any of the consequences that would come from actually confronting power.
I make lots of compost for my own use. Composting is at best delaying carbon release. As soon as you stop recycling materials the carbon will be released to the atmosphere. In permaculture circles the goal is to close open loops of waste/resources. If you want to permanently lock carbon in your soil, and improve fertility, make biochar. Throwing charcoal in your compost is the easiest way to make it into biochar. It really works and is a permanent amendment.
If you wanted you could even weigh the raw charcoal to quantify the carbon you have sequestered.
None of the loops are open in the sense that it's all within the earth system as a whole. The issue is extracting carbon from geological deposits. Stuff about farming and methane is temporary and short term.
I don't mean to suggest we shouldn't compost or recycle things. Just that such measures are only indirectly related to carbon emissions.
We either stop extracting hydrocarbons from deep within the crust or else the problem will persist. (I guess technically we could industrially sequester the equivalent but that would almost certainly defeat the cost-benefit of extraction.)
In that sense even hydrocarbons are closed loop. Earth made the oil deposits so we aren't adding anything that wasn't already here. The carbon we pump into the atmosphere will eventually become oil again.
My point is that the timescale of a given loop is what matters. Specifically, extraction of geological deposits has a timescale (and thus an equilibrium) that is highly undesirable for us.
Sorry to be a debbie-downer but
the composting process is also a source of greenhouse gas and air pollutant emissions.
From your source:
> Effective pile management and aeration are key to minimizing CH4 emissions.
So it sounds like a correctly managed pile is not a problem.
Also, I have a hard time believing my composting in my backyard is in any way worse than my sending the same food scraps to a landfill.
Thats great that you can correctly manage a compost pile. That level of conscientiousness is a quality that doesn't seem common across the population.
A positive thing about a landfill is that it can take advantage of centralization by capturing biogas created by the large quantities of biodegradable material deposited.
https://www.sciencedirect.com/science/article/abs/pii/S03603...
So are humans (we breathe out CO2 constantly!). A process emitting greenhouse gases is not an inherent reason to eschew it, so long as the entire end-to-end process isn't net-positive.
Use that compost to fertilise a tree, and you are still net negative on carbon, versus sending those food scraps to the local trash incinerator.
It's all a cycle, They put carbon in, they release carbon out. At least the average American is doing a commendable job in increasing their personal carbon sequestration.
There simply is no solution to this problem. We would all need to stop driving, flying, and eating meat. Most families (in the US, anyway) would suffer unemployment and starvation if they couldnt drive to work.
Humans will continue to do whatever is needed to survive,, and that currently involves driving, flying, and eating meat. They will only stop when those behaviours are either not possible, or hinder survival.
Very alarming. I feel like especially the West is regressing on climate change with the rise of the far right (https://www.politico.eu/article/robert-lambrou-alternative-f...)
I don't know what to do.
Work on local things to make your own city better. Plenty of stuff that's not too difficult, even if it won't fix everything:
* Multifamily housing is much more energy efficient. Is it legal to build throughout your city, or does zoning prevent it?
* Is there good bicycle infrastructure so people don't have to drive for everything?
* Does your city still have expensive parking mandates that lock in car dependency? Get rid of those. They also get in the way of places becoming more walkable.
* This one hurts, but: eat less beef.
* Advocate for good transit as another way for people to get around without driving a personal vehicle.
* What can be done in your city/region to electrify heating for homes and businesses?
* What can your region do to build more renewable energy capacity?
Those are all things where even a few voices can sometimes make a difference.
Individual habits will not be decisive in fighting climate change. Telling people to follow this advice will (a) inconvenience them in the short term (b) lull them to a false sense of security that they are fighting climate change (c) set them up for disappointment when climate change happens anyway, and (d) worst of all, these suggestions let the real perpetrators off the hook.
If you want to see real progress on the climate, a few thousand people changing their daily habits is not enough. Governments need to take action and hold industry to account. That looks to be an increasingly unlikely event, but that doesn't justify taking ineffective action instead as a placebo.
It reminds me of the '90s when we are all told that recycling was necessary for saving the environment. Decades later, we'll still spending time sorting our garbage, despite evidence that no one wants recyclable waste, it still ends up dumped somewhere, and it costs more money to handle. [1]
But individual behavior is not about preventing climate change, it’s about doing what’s right. It’s wrong to pollute the environment, one way or another. A single person not stealing won’t reduce the crime rate in a country yet it is the right thing to do.
That's not a fair comparison. Everything we do affects the environment. The goal is to limit that effect where it matters. It's not ethical, it's practical.
Apart from eating less beef, every single suggestion in the post your are responding to is about infrastructure and advocacy, not individual habits.
And almost all of them have plenty of other benefits too:
Multifamily housing is generally cheaper in high land cost areas. It helps solve the housing shortage.
More bikes and transit and fewer cars means cleaner air and fewer traffic deaths.
Less fossil fuel usage in general means less pollution.
Cities that use land more efficiently tend to be more walkable, pleasant, and don't gobble up things like farmland or forests outside the city.
Come to think of it, less beef is probably better for your health, too.
> less beef is probably better for your health, too.
Won't matter when it's 120 degrees F every day.
My advice is to install air conditioning, and choose a place to live that will be affected as little as possible. Avoid the Maldives or New Orleans, perhaps choose somewhere a little hilly and cool with good connectivity.
Great suggestions. I will pass your advice on to literally all of humanity.
That's what will happen, you might as well get ahead of the rush.
> Apart from eating less beef, every single suggestion in the post your are responding to is about infrastructure and advocacy, not individual habits.
Exactly. That's why it's ineffective to evangelize this as individual effort. If you want to live in a multifamily home, they have to be zoned, funded, and built. That requires lobbying the government, moral rectitude.
I did not write 'individual habits' - you did. Things like zoning are not individual choices at all. But they are something that you and a few friends might be able to influence at city hall.
None of this "lulls" involved people, nor lets anyone off the hook.
These are things that ordinary people without a lot of money or power can work on today in a country like, say, the US, where the federal government is in the hands of evil people and is not going to be doing much in terms of climate change in the near future.
The federal government may be a lost cause for the moment, but your city or state might provide an avenue to get some things done. Those things won't fix the whole problem, but they're still progress, and the connections you make while doing those things will be useful in future, bigger fights.
> These are things that ordinary people without a lot of money or power can work on toda
I agree: people can work on this individually. And it won't make a lick of difference.
How many items on this list require government action? How many require corporations' cooperation. What am I going to do, build the bike lanes myself as a hobby?
The work is getting your local or state government to do the things. I thought that was quite obvious.

> these suggestions let the real perpetrators off the hook.
This can't be said enough. It simply cannot be said enough. It cuts right to the heart of how we view the world in the west: as autonomous, separate individuals, with no communal counterweight and certainly no model of power (some entities in the world have vastly more power than others) We assume that because our constitutions grant us equal rights or whatever, we all have equal responsibility and equal power.
But polluters, the biggest sources of emissions, have way more power and way, way less responsibility. And yet we continue to tell ourselves to focus on our own individual behaviors to combat global heating. The effects are real, but tiny, and our elites continue getting away with our annihilation.
Great list!
For those in the US, I'd add lobbying your congresspeople to support the revival of the Energy Permitting Reform Act. It's something that didn't make it across the line before the end of the last congress, but basically, making it easier to bring new generation capacity on the electrical grid disproportionately benefits renewables, because they make up the vast majority of wattage waiting in the queue. As we've seen by the explosion of deployment in less regulated grids (Texas, and most of the world), the economics now favor solar+storage and wind, we just have to let people build as much of it as they want to.
I would add:
* Plant more trees
> I feel like especially the West is regressing on climate change with the rise of the far right
Is it the "far right"? Or is it that technology and fertility have actually lowered the risks substantially?
Solar plus batteries, right now, seems to be the cheapest form of new energy. Given that, you would expect most of new energy to be "green". (And if you look at the stats, that seems to be coming true.)
Electrification of transportation is happening quickly. China is cranking out cheap electric cars that are generally better than ICE cars of yesterday. And the world seems to be transitioning.
And fertility rates are dropping everywhere. So the amount of people we will need to support in the future continues to decline.
I've mostly stopped worrying about climate change. Not because I don't think it is real. But because I think we are clearly on the path to mitigating the worse scenarios.
The far right leader of my country just created a new policy forcing the military to buy electricity from coal plants, even when it's more expensive
> I think we are clearly on the path to mitigating the worse scenarios.
This evidence based article published in one of the worlds top scientific journals comes to the opposite conclusion.
> Is it the "far right"?
Yes, it is. They're committed to "Every molecule of hydrocarbon will come out". [0]. They keep saying this to us, and we don't seem to believe them. I like your optimism, and I'm not denying a lot of what you're saying -- renewables fast becoming the cheapest energy. But that's not deterring people: the far right here in the US are about to dismantle the government's legal rationale for regulating emissions. They're laughing at us right now, doing victory laps. They're telling polluters to take the gloves off.
These people are terrorists, extremists, and they're in charge of the world's single most powerful economy and military. They're obsessed with domination, with doing violence to the weak and the poor and to nature. It's pure Freudian thanatos.
It's just hard to take your position.
[0] https://theecologist.org/2023/dec/05/every-molecule-hydrocar...
I'm not sure exactly what you mean by the "far-right", but you seem to be implying this 'every molecule' quote (or more charitably, the goal) is of the "far-right" in the U.S. In reality the quote is from Saudi energy minister Prince Abdulaziz bin Salman. I mean, I wouldn't be terribly surprised if Saudi Arabia is considered far-right governed but I doubt your wording is giving the correct impression to readers.
Yes, I know it's a Saudi quote. They're also far right. They're bosom buddies with the same right-wing (Democratic) and far-right (Republican) US economic and governmental elites for decades. I don't think anyone would dispute this. In fact, it's so humdrum a set of facts that I think the burden would be on someone else to show that "no, actually, US elites are not into the whole 'every molecule of hydrocarbon' thing". But their behavior doesn't indicate that they disagree.
It's thus, yes, the correct impression for readers.
This is all rational thinking if you don't know or care to know the actual scale of global warming
Yep, its the far right.
The Heritage Foundation (Project 2025, far-right, anti-climate) is working with the Heartland Institute (spreading climate science denial across UK / EU) / Alliance for Responsible Citizenship (ARC, Jordan Peterson)
They do not like EU rules that hold US firms accountable to climate laws.
https://www.desmog.com/2026/02/10/donald-trump-uk-eu-maga-sl...
Sorry, I'm not saying the far-right isn't (whatever) anti-climate change.
I just meant that I don't think the lack of concern is necessarily due to them. I think it may have more to do with the reality that we are already on a good path.
Bill Gates famously wrote a "note" about it last year: https://www.gatesnotes.com/work/accelerate-energy-innovation...
There are actions you can cheer on, like China's quick adoption of renewable energy. You can't make it happen yourself but you can bring peoples' attention to good things, encourage those within your circle of influence, and vote for representation that shares your views.
As for what "we" collectively can do... let's assume you are speaking of areas of research. We may need to focus on researching adaptation techniques for the areas that are going to be the hardest hit, or that have the fewest resources to cope. It's a sad topic but it may be needed. Assume the worst, hope for the best, and plan for what you can.
Significant emissions are from ground transportation. Advocate for walkable neighbourhoods, bike infrastructure and public transit.
Seems China is cooking atm. If solar power and battery tech continues at this speed and their nuclear ambitions pan out, fossil fuels will be economically non-competitive (if they aren’t already). China EV momentum is incredible.
So still some hope I think! And it’s possible the populist “dumb dumb bricks” crew will decline in popularity when the inevitable lack of tangible improvements continues. Though since we are dealing with dumb dumb it may take a while
What's most alarming IMO is that we're probably (still) systematically underestimating the effects of climate change.[0]
The idea that this current apocalyptic prediction is expected to be better than reality is... not comforting.
this is like a tiktok rage bait way of thinking. western nations have largely peaked on carbon emissions. china is slowing down and will peak soon. there are a lot of countries that still are growing in emissions, sure, but you are not looking at this scientifically.
Scientifically according to the article, the world is on an emissions path to 2.8°C warming, not accounting for the extra rate of warming we've seen in recent years. And this puts us at greater risk of hitting tipping points into an even warmer planet. So the status quo isn't cutting it.
China is nowhere near peaking, nor is the world.
https://ourworldindata.org/profile/co2/china https://www.statista.com/statistics/276629/global-co2-emissi... https://ourworldindata.org/co2-emissions
It's true that the West did peak in 2007 (as did South America, India, and Africa), but Asia's emissions are so massive that they more than make up for all of the reductions of the rest of the world. That last link I posted makes clear how big the problem with China is.

> I don't know what to do.
As a 52 year old who never believed we would take climate change seriously (and who is more convinced than ever I was correct as society actually regresses on this issue) I did what I had to do -- I purposefully didn't have children.
Good luck to those of you who did.
This ain't my problem. I'll be dead (or close enough) when the shit fully hits the fan and won't have doomed any offspring to the upcoming migration/resources wars
The answer to that question is always the same. Join a party and become politically active. Or, if you really can't find any party that represents your views, join an NGO and become active in it. If you're too lazy for that, consider paying an NGO that does spectacular actions that have a public impact. And never vote for any parties that don't do anything for better climate control, of course.
You work in software, right? Then you can donate some money to enviro orgs.
Not an expert in any of that, but I think overall impact may be greater if people with sufficient means take a more hands-on approach that grants visibility of where money is going. I lean environmentalist be the truth is that there’s a good deal of well-marketed snake oil in the environmental space.
The issue with quibbling over impact is my experience is that people end up doing neither. I recently started a Master's in ecology so I don't have a good idea of what's cost effective right now but I know the field is pretty shockingly underfunded (both for general research and conservation projects). I learned the "fun" fact recently that bird populations in the US are down ~30% in the last 55 years.
A fair assessment. Doing nothing is not the answer to the risk of doing the wrong thing. It's probably worth some time spent on due diligence when selecting groups to donate to, regardless.
If you are a US citizen, voting Trump out might be unironically the most significant decision your country could make for the next 100 years of mankind.
Not because the alternative is so great, but because Trump is so horrible that it's not even a question. We really don't need someone who doesn't even acknowledge climate change in charge of the world's biggest economy.
Trump is ineligible to run for a third term. The time to vote him out was 15 months ago.
Fear and egoism is probably causing the rise of the far-right, fear of not having enough, and egoism of "Why do I have to share?" (and being dumb enough to believe "make it great again" lies). And then the idiotic "center" who doesn't want to lose voters start moving to the right. With the decaying planet less capable of producing food, there'll be less, and there'll be more of that scarcity mindset (although do we even have scarcity, maybe it's just the uneven distribution, with billionaires eating cows that's been fed grass that's grown with the purest glacier water flown by helicopter from the Swiss alps...).
In one aspect, the autocratic rule of Xi Jinping has a positive: "We're going to cover the whole mountain with solar panels, and force electrification of cars." and there's no busybodies protesting and threatening to vote his party out of office.
Ever admitting the positives of autocrats for their apparent efficiency disqualifies surrounding suppositions. And that's not an ad hominen, that's just Bayesian.

YC has always been about cashing in on the latest grift, and nothing more.
Yet here you are.
This is one of the key sentences:
> Policymakers and the public, however, remain largely unaware of the risks posed by such a practically irreversible transition
Most people still underestimate what it means for the earth system to change from the current stable state into another state, which might need many years to become stable again. And that new stable state might be a lot less favourable for us humans.
> might need many years to become stable again
People really fail to grasp the significance of this part.
One of our most common apocalyptic fantasies lays this out quite well: nuclear annihilation. The common narrative is about the post-apocalyptic world and rebuilding. But this presumes a new normal has been established.
With climate change we will continue to experience more extreme changes at a faster rate over time with no chance of a "new normal" in our lives.
It took hundreds of thousands of years for humans to develop agriculture. It's no coincidence that this development happened during one of the most stable periods of climate the planet has ever seen. People love to wax poetic on human adaptability, but we were effectively playing on "easy" mode.
While the other side of climate change might be a more hostile earth, the transition period will be worse because you can't adapt. In our lifetimes we may live to see a period of record heat waves in Europe, followed by a transition of Europe to that is dramatically colder (and who knows, maybe back again).
The other major problem is as stability decreases so does our ability to predict the future. It's hard to even know what we might be facing in the coming years, but high variance is usually not great for complex life.
> the transition period will be worse because you can't adapt.
As far as agriculture goes we can adapt but the cost would be exorbitant. Vertical farming is technically doable.
It's not that policymakers are unaware. It's that some of them are allergic to true things that they find inconvenient, and have made false premises a pillar of their platform. Calling that "unaware" is giving them too much credit and understanding.
I think it's both. That large shifts on a global scale of everyday things that we take for granted as well as historical differences on a geological time scale are genuinely difficult for non-experts to wrap their heads around.
And also as you say that many politicians are disincentivized to try in the first place.
> It's that some of them are allergic to true things that they find inconvenient, and have made false premises a pillar of their platform.
Sure, if by "some" you mean "virtually all".
Nope, attempted bothsidesing rejected. By "some" I mean "some". Not everyone in politics treats truth as optional. Those who don't should be lauded.
Thinking this is "bothsidesing" is you contributing to the problem. The Democrats and Republicans have both abandoned scientific rigor on this topic. When either talks about it, it is almost purely an excuse to smuggle in unrelated policy objectives.
A group of politicians can have strong disagreements where none has a grasp on reality. That is where we are with climate change. It is one of the reasons I stopped working on it at a policy level.
I am not suggesting that all politicians on one side are good. I am suggesting that ignoring truth and reality as things that matter is a trait with very strong correlations with political party, and shouldn't be generically chalked up to "politicians" in general.
As Asimov said: "When people thought the Earth was flat, they were wrong. When people thought the Earth was spherical, they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together."
Most policy makers will not live to bear the fruit of their labor.
Many may also believe that they and the only parts of their con$tituency they care about will be able to avoid the consequences. And some may have come to believe the party line; if you repeat a falsehood often enough as a loyalty test, you may forget that it's a falsehood.
It is difficult to get a man to understand something, when his salary (power, class) depends upon his not understanding it
I think most people bet that they'd be dead until that transition happens, so the problem won't be theirs to address.
It's a classic multi-agent coordination problem. Should I stop taking jet liners and eating meat, when everyone else is anyway?
(Edit: purely illustrative rhetorical question, but I appreciate the responses)
To be fair, if we cut beef, lamb, and dairy, we get 80% of the GHG benefits of going full vegan. Beef and lamb are really GHG intense.
So you can keep your animal proteins: it'll just be eggs, fish, poultry, and pork.
For me, it's a hard problem.
For business trips, the choice is between two hours and two days, and unfortunately my body goes haywire if I don't eat some meat at least a couple of days per week (talking about 200g/300g total though. Not kilos of it).
On the other hand, I'd happily take trains as more high speed lines open in my country, and reduce meat consumption to bare minimum my body can tolerate.
For personal transportation, going fully electric won't be possible due to my circumstances, but I'd happily switch to a hybrid which would convert 75% of my in-city travel to electric (which I'm actively planning to do).
I also work on projects which tries to reduce footprint of data centers and computation, so there's that.
> my body goes haywire if I don't eat some meat at least a couple of days per week
Isn't this just a nutrient deficiency in whatever you were eating instead of meat? Meat is "convenient" because it's high in a wide variety of minerals, vitamins, essential amino acids, etc. that your body can't make. (The animals mostly can't make them either but guess what livestock eats.) There are plants that contain each of them, but few if any that contain all of them, and then if you're missing one you're going to have a bad time. So the problem there is almost certainly that you need to eat some different plants than that the thing you were missing is only found in animals.
I can't speak for the OP but it is well-established that there are significant genetic adaptations to the amount of meat in the diet, or a loss of genetic adaptation for metabolizing some plant staples. This is no different than the genetics that cause significant variation in the ability to metabolize legumes, lactose, alcohol, etc. Local optimizations.
There are ethnic populations that have reduced capacity to efficiently metabolize some plant-based diets due to thousands of years of selection pressure (or lack thereof). A diverse plant-based diet won't kill them, they simply lack the enzymes to have a good experience with it because for thousands of years they had little use for those genes.
It is a relatively small population globally, as it tends to coincide with regions that weren't conducive to supporting large populations thousands of years ago. The current distribution has significant overlap with the developed world though.
I have to imagine that someone with meat-adapted genetics is going to suffer quality of life issues on a purely plant-based diet. Everyone has a set of foods like that.
Might be lack of understanding of essential nutrients and associated planning. But also might not be related to that at all. The gut microbiome is impacted by your food choices, varies from person to person, and can have severe impacts on your overall health.
Nope. Some aminoacids and compounds are only present in meat. These aminoacids and compounds are the ones which boosted our brain capacity and allowed us to evolve to that point.
I eat (and like to eat) tons of veggies, yet I feel my brain capacity declines and I crave esp. meat if I don't eat it for a long time (for two weeks or whatnot). As I said, I don't need two ribeye steaks per week. My body is very good at signaling what it needs, and I prefer to listen to it.
What I eat is Mediterranean cuisine 99% of the time, and it's pretty well balanced, yet eliminating meat is not possible for me. So, my diet is not junk food peppered by meat. It's mostly veggies and legumes (beans, lentil, whatnot), peppered with meat. Yet, I need it, and this is something I tested over and over more than two decades.
On the other hand, my wife is completely opposite of me. She can go a month or so without meat. So, not every person is the same, and assuming that every human being works the same is a big mistake made by modern medicine. For example, my brain chemistry is also different and I consume B12 much more than a typical human, so I need to use B-complex supplements more.
> Some aminoacids and compounds are only present in meat.
Which ones specifically?
https://en.wikipedia.org/wiki/Essential_amino_acid
All of those can be found in plants.
> Nope. Some aminoacids and compounds are only present in meat.
https://en.wikipedia.org/wiki/Essential_amino_acids_in_plant...
Notice that many of the plants high in some of these aren't that common, e.g. what percentage of people regularly eat pumpkin seeds or spirulina?
> So, not every person is the same, and assuming that every human being works the same is a big mistake made by modern medicine.
It's not that you need the same diet as every other person, it's that you have to eat the specific things you need, which a random selection of plants may or may not contain in the right amounts.
> For example, my brain chemistry is also different and I consume B12 much more than a typical human, so I need to use B-complex supplements more.
B12 in particular is a pain because it's only produced by bacteria (commonly found in soil) so the options are unwashed vegetables, meat from animals that eat unwashed vegetables, or supplements. And on top of that because of the way it's absorbed, a B12 pill either has to be taken multiple times a day several hours apart or has to be 100x as much to make up for the absorption rate falling off a cliff after a threshold amount which is below the RDA.
It’s hard to convince people not to eat food and take a plane when billionaires do whatever they like at 1000x the carbon footprint, when millions of people drive to work and when base load power is built on fossil fuels. To me eating protein and taking a plane seem benign.
I agree.
If the plane doesn't use synthetic fuel that's a political problem that I can't realistically solve as an individual.
The methane from raising animals exists in an overall equilibrium. It isn't extractive and the total magnitude of the effects of that chemical system is comparatively minor.
They are most definitely aware. They are willfully ignoring this but they are not ignorant.

What is generally not understood is that our current icehouse phase is rare.
'A "greenhouse Earth" is a period during which no continental glaciers exist anywhere on the planet... Earth has been in a greenhouse state for about 85% of its history.
'Earth is now in an icehouse state, and ice sheets are present in both poles simultaneously... Earth's current icehouse state is known as the Quaternary Ice Age and began approximately 2.58 million years ago.'
https://en.wikipedia.org/wiki/Greenhouse_and_icehouse_Earthh...
The _state_ isn't alarming, it's the rate of change. The transition is happening on a scale of human lifetimes instead of geological time.
Yeah. The XKCD "Timeline of Earth's Average Temperature" is, I'm pretty certain, the most frightening chart I have ever seen.
Precisely. Humans can adapt to almost anything but we can not do it fast enough with 8 billion+ people.
> Earth has been in a greenhouse state for about 85% of its history.
And during those periods there were no human beings. And no agriculture, or unstable globalised economiies, or dense urban societies vulnerable to disruption.
It is, of course, interesting that our planet has this long, varied existence that pre-dates us. But it is of little use in understanding how to get us out of the hole we're in. And it is arguably dangerous, because it misleads people into thinking that we have the capacity to adapt to such conditions, when we manifestly don't.
To put a different shade on the meaning, this climate period is rare, easily disturbed, and difficult to restore even with vastly more powerful technology.
The more common greenhouse state is unlikely to lead to a Venus runaway, but it will be hostile to us.
We might very well require the rare climate, and perish in the common.
Its not a "risk".
Water vapor (clouds) is a stonger greenhouse gas than carbon dioxide. We already got measurably higher temperatures, so we also have higher water evaporation, and from the last 5 years it looks like it happens every year.
So the runaway is already happening, until something stops it near hothouse conditions or hopefully earlier than that.
Thank you for saying this. If you want to know the answer to what causes climate problems, you need to go back to the era of dinosaurs, where CO2 levels were multiple times higher than today. Trees could thrive because they could breathe in a lot of CO2. Dinosaurs got so big because there were plenty of food. How could dinosaurs happily live with such high CO2 levels? The key is that there were plenty of forests. Peter Wohlleben's book "The Power of Trees: How Ancient Forests Can Save Us if We Let Them" explains how forests naturally circulate water.
The climate system in those prehistoric times was in a different stable state. The world that we live in has different ecosystems that are well-adapted to the current stable state and we will likely face a mass-extinction event once the ecological scales tip over.
The problem is also the speed in which the CO2 levels are rising. Such a massive change in such a short geological time is very unusual.
[dead]
Water vapor (clouds) also reflects sunlight. So it's complicated. We know the planet has had higher CO2 and higher temperatures in the past, and it did not "run away"
No citations to hand but Antarctica used to be temperate rainforest and many of the conditions of present day tropical rainforests and savanna could be found much farther from the equator.
The paleocene–eocene thermal maximum makes for interesting related reading. https://en.wikipedia.org/wiki/Paleocene%E2%80%93Eocene_therm...
We can't say for sure that the current feedback loops will be identical to those that did or did not exist in the past. Differences in the initial state could result in different outcomes.
For example was there as much methane trapped in the arctics during the last time CO2 was high?
Does the rate of the increase of CO2 and temperature have an effect? Because it's currently getting hotter far faster (absurdly so) than any other period we have records for.
It might not run away to infinity, but it may well run away in the sense that the rate of change could continue to increase even if humans stop contributing to it.
> Water vapor (clouds) also reflects sunlight. So it's complicated. We know the planet has had higher CO2 and higher temperatures in the past, and it did not "run away"
Yes. But stars like ours burn brighter as they move through their lifetimes, and the Sun is a bit brighter now than it was back when we had higher CO2 levels. That's why a runaway GHG didn't happen back then, but is basically guaranteed to happen within a billion years.
So… the sun is hotter now than it was what… since the 1950s? The 1850s? The Jurassic period? What scale is do you need to make this claim reasonable?
Also, I see a lot of things presented as facts in your comment, you seem to have convinced yourself quite thoroughly.
10% every billion years. So negligible on our timescale, but it is significant if you talk about ancient climate conditions like this thread does.
complex life on earth is half a billion years old (cambrian explosion 550ma ago), so the sun shouldn't be that much of an factor.
It doesn't matter if the top of the curve flattens out, if we can't survive outside of the bottom part that looks exponential.
True runaway (i.e. oceans boiling / Venus) cannot happen on Earth unless you significantly increase incoming radiation stream (or alternatively halve the planet's albedo).
The runaway effect is scary b/c at certain temperature (~400K) atmosphere consisting predominantly of water vapor looses its ability to radiate out more heat up until 1600K.
[0] https://www.nature.com/articles/ngeo1892 (see fig. 2b) (edit: the figure: https://imgur.com/a/ytoEXzd)
edit #2: I've measured some pixels and the starting runaway temp is closer to 315K / 42C, damn
Are you certain we can't become Venus? Venus itself has such a high albedo that it effectively receives less radiation than Earth does.
And that's just one of the many positive feedback loops.
The CO2 graph over decades is painfully clear.[1] From 321ppm in 1970 to 428ppm in mid-2005, measured in Hawaii atop Mauna Loa, far from any major CO2 sources. Everything else is noisy and statistical, but the CO2 measurement increases very steadily.
Yes, and the scary thing is that soon the atmospheric carbon PPM will be high enough to start affecting how we think, act, and feel on a day to day basis.
Surprisingly, no. Humans adapt to higher CO2 concentrations over a period of days to weeks. Submarines run as high as 5000ppm, which is way above normal atmospheric concentration.[1] Many indoor environments are above 1000ppm.
This seems to be like high altitude adaptation. It's going back and forth between concentrations that causes problems at moderate concentrations. The adaptation doesn't happen.

One massive mistake scientists made, was to market it as "global warming". Every climate-denier I've ever met, has pulled out the "If the earth is getting warmer, why are our winters still so cold? Check mate" card.
I live in a colder climate area, and every. single. time. we get some cold weather, these people will come crawling out of the woodwork to point out that "global warming is hoax!"
And, unfortunately, due to the extreme rise of populism the past 10 years, the "climate change is a hoax" mentality has been allowed to prosper.
Yes scientists made a mistake by calling something what it us. Definitely not the morons who don't understand the difference between weather and climate.
So maybe the people who aren’t having kids due to climate change were right after all?
The problem can now only be solved on the supply side. Cut the production of oil and gas below the planet's natural carbon sequestration.
The low prices of solar and batteries are a glimmer of hope. For many regions it's now the cheapest source of electricity.
You mean cutting into the profit/MONEY of these large corporations? How will they survive!?

When I want to motivate myself I look at this https://www.theclimatebrink.com/p/the-scariest-climate-plot-...
In this thread people talking about a civilization-scale collective action problem that we've never come close to solving, and telling us to use paper straws or regulate the oil industry.
The only even theoretical solutions are:
- A magically effective totalitarian state that watches everyone inside a panopticon.
- Magically undo the damage with a technological breakthrough.
- Immediately leave Earth.
Nothing new under the sun.
We can't cut emissions fast enough politically, but we can race towards economically viable fusion power which would solve the problem from the supply side and would make industrial scale carbon sequestration not insane, for a century or so, until waste heat itself can't be radiated fast enough even in 250 ppm CO2 atmosphere - but that's a problem for the XXII century.
Economically viable fusion power uses the fusion reactor in the sky beaming energy to us for free that we can collect with relatively cheap, simple, decentralized, solid state, and extremely long lasting (decades) power transmission recievers.
No disagreement, but nights and clouds are inconvenient and remedies are also expensive-ish. We need both.
Why solar aficionados consistently forget about the night and intermittency in general? It's not like diurnal and seasonal storage will pop up for free and the energy grid will reorganize itself.
How about economically viable fission power, right now.
That's the thing, can't be done
France, Sweden and Ontario exist.
https://app.electricitymaps.com/map/12mo/monthly
It literally has been done.
Past performance does not guarantee future results.
Building out nuclear requires political will and deregulation which today is not attainable in the west. China is the only one actually building reactors, but that isn't enough.
I think the answer to this is ultimately economic, and that people will only change their habits when it comes down to what costs them money. Naturally this is because culturally, we have defined our life in this way, and those who value money benefit from the existing culture.
People who treat money as the only resource they need to navigate life stand to lose when things get expensive, but stand to lose even more when other forms of resource (energy, family connections, community) are needed.
As an extension of this I think extreme wealth inequality won’t ever be solved by a more equal distribution of money, and only can be solved by a devaluing of money as compared to other resources and thus a reduction in the power that money has. It’s not surprising then that billionaires end up spending their money on what gives them more control rather than what is a sensible monetary decision, like Musk purchasing Twitter.
I dont understand this line of reasoning at all. The holocene looks like the most recent in a cycle of short warming periods that has been going on for over 1M years. There is little reason to think its stable. One could argue that we should push warming to prevent the coming glaciation. I rather suspect that would hasten it instead, but the runaway hot house thing is not supported by the historic record. Perhaps the collapse of the AMOC is what tips it. Either way, saying its the most whatever in 125K years is irrelevant since we should be aiming for conditions from before the ice age. If you frame it in the longer history briefly mentioned in the article it looks quite different.
Just price in the externalities and it probably solves itself

At least considering only temperature, it seems changes are never going to be irreversible since both stratospheric aerosol injection and intentional nuclear winter should always be able to cool down global temperatures
>Despite decades of research and sophisticated computational climate modeling, the magnitude and pace of these events have surprised scientists, raising questions about how well current climate projections capture risk.
When this always-revise-in-one-direction phenomenon happened with the electron charge, it was considered a priori "proof" that scientists were fudging their data to match expectations. The Millikan Oil Drop Experiment is still studied in fundamentals of science class.[0]
If climate scientists are constantly revising their predictions upward, then this is equally "proof" that climate scientists are under pressure to revise their estimates downward. Far from being "alarmist," such terms are actually cudgels used to discourage climate scientists from making their data look too bad.
The result is the predictable fudging of climate data to look better than it really is.
[0] https://en.wikipedia.org/wiki/Oil_drop_experiment#Millikan's...
What about the possibility that the models so far have always been wrong and if they wrong in the wrong direction you would never hear about them?
Precisely, it's just a selection effect. There's always uncertainty, and scientists are heavily incentivized to "prune" models that show large effect sizes. The result is the observed systematic underestimations, punctuated by (suspiciously monotonic) upward revisions any time the new data comes out.
Carbon tax. Stop subsidizing fossil fuels.
One of the solutions is to stop the ai hype, as the excessive electrical needs it creates are obviously not helping with the climate.
No worries ladies and gentleman, AI will solve it, insert coin, or better throw another trillion at it and all will be solved.
AGI is here
[dead]
Are there any attempts to start geo-engineering to fix this? I'm assuming there will be no attempt to stop dumping carbon into the atmosphere, can we at least do something to take it back out? Can we use solar or renewables to possibly do that at scale?
Putting sulfur into the right layers of the atmosphere seems to be the currently best viable options. It's not overly expensive, either. It acts fast and is reversible.
https://en.wikipedia.org/wiki/Stratospheric_aerosol_injectio...
Dumb question: would this also lower solar panel yields?
Thank you. This reading lowers my anxiety. I believe we'll rationally - and in a hurry - come down to this kind of solution. It makes solid sense.
I'm sure that are no adverse effects.
This reads like someone with the means to eat good food eating junk food and then putting themselves on weight loss drugs to counteract the effects. I'm sure temporarily it might work but I don't believe that the shocks that produce meaninful cooling effects are without consequence - in fact, I suspect they double the consequences by adding yet another factor to the destabilization.
I could be wrong, and it could a short term solution to stop the bleeding, but I have a deep suspicion of adding more things to the atmosphere given our history with the CO2 in question, tetrafluoroethane, etc.
Lookin at the wikipedia it does sound a lot like "chemtrails". They describe airplanes as being able to disseminate these aerosols and these days when I look up at the sky there is always a straight line of "cloud" forming behind airplanes.
So far all of the carbon capture techniques (apart from growing forests and keeping them protected) have been pretty unsuccessful, and/or don't scale well.
That leaves us in the realm of solutions that may be very likely to disrupt our ecosystem themselves, like genetically-engineering algae/phytoplankton to improve ocean carbon sequestration
> apart from growing forests and keeping them protected)
I’m in a loop. I must be.
How are people still basic at this? No. Forests are not “carbon capture” devices.
Plant a big forest and “protect” (which means thinning it, unless you are California) and in 100 years most trees have died, rotted, released their carbon.
There is so much wrong with the alarmism here, so much hand waving away of scale when it is inconvenient… that it’s like people are doing more damage than good when they jump up and down over this stuff.
It’s almost like if the jumping up and down and alarmism has a different purpose, a whole separate game removed from the issues at hand.
> in 100 years most trees have died, rotted, released their carbon.
And more trees have grown in their place, capturing an equivalent volume of carbon. Just because the carbon storage isn't static, doesn't mean it doesn't work.
The carbon in our atmosphere is already in the atmosphere and it won't go away. So there really is nothing more you can do other than take it out of the air and store it somewhere for as long as you can. Trees are a good way to store it until we have better technology/can handle climate change better
No. Pick a timeline that is influential, short or long. If it’s long, trees don’t capture carbon. Not in any scenario of population growth, which inevitably leads to some edgelord reductionist “maybe we should all die then for what we’re doing to Gia!” trite.
This “climate is a 100 years” thing while using ice core samples to make your case is not in support of science. It is in support of politicians.
The latter I’m personally getting sick of. And the people that can separate them, harm the former.
> Not in any scenario of population growth
We're not really in a scenario of population growth - there is a direct correlation between being relatively well off and having less kids. Basically every developed nation hit peak population a long time ago, and the faster we pull other nations out of extreme poverty, the sooner their populations will start falling too
Even the most fatalistic estimates have world population peaking at 10 billion.
I don't think carbon capture / sequestration is going to do enough, but if we continue slipping into this trajectory I think there will be more support for changing reflectivity (spraying sea water, or putting particles in the stratosphere).
Stratospheric aerosols: the dangers of this seem overblown. It is milder than a volcanic eruption. It seems like a reasonable thing governments should be attempting.
There are currently no power efficient and scalable ways to remove carbon dioxide from air or water.
Renewables are considered woke technology which mock old and masculine fossil fuel tech, which feel threatened by all these white spinny things, hence renewable energy projects are being actively discouraged or canceled altogether.
You know, we'd be all woke and weird if our cars don't have 8 cylinders and make wroom sounds. Same for our chimneys and power architecture. Woke electrons should be banned. We need masculine, fossil based electrons, which are more powerful per electron than wind/solar based fluffy/hippie ones.
The rich don’t care which side you’re on, as long as you’re fighting each other.
I don't play that game. I only do what I can do with what I have and don't care about losing time with pointless fights.
I may not be able to save the whole planet, but at least I'll leave my area a bit better as my capacity and time allows.
Both sides aren't fighting each other, one side has turned themselves into a weapon for rich pedophiles to attack the other side with.
Notably, both sides held that exact view in recent times.
> Renewables are considered woke technology which mock old and masculine fossil fuel tech...
This is mostly a US problem at this point. The rest of the world is adopting renewables considerably faster than anyone expected (and despite the best efforts of the current administration, the adoption curve is accelerating even in the US).
That said, it's still apparent that even optimistic estimates of renewable energy adoption aren't fast enough to fix the climate crisis on their own.
> This is mostly a US problem at this point.
Yeah I know, and I'm not from that side of the ocean. I worded my comment like that since most users here are from the US.
electricitymaps paints a nice picture, though. We'll be using them in a project, so I'll be able to see the nitty gritty details soonish.
At least some of us are trying. Maybe we'll fail, but not all of us are that ignorant, and that's better than nothing.
Needed to happen 30 years ago.
Now it’s drill baby drill time.
I really think the key to addressing climate change should have started 20 years ago in a lot of primary schools, whereby the curriculum includes subjects that are more tailored to solving problems with capturing or converting C02 (eg sciences) so that these students are thinking about these problems when graduating and starting businesses to solve the challenges (hopefully with gov incentives at same time).
We have had the technology to decarbonise the grid since the 1950s and we have known about the problem since the 1970s. Politics however has driven the use of CO2 instead of nuclear energy and required the drastic development of high end wind and solar. Even that wasn't enough, it also had to get considerably cheaper than CO2 producing energy sources and the entire time the entire worlds population has been subjected to massive amounts of propaganda to keep burning oil, gas and coal. This transition was possible 55 years ago when the problem was first surfaced, the political will just wasn't there so it didn't happen.
Its not an education issue, it has always been governments getting in the way and refusing to change the power source. its why I think Solar will win out, it can be deployed on an individual house level unlike everything else and that changes things enormously.
eh... imagine a planet scale messmer plan... too bad petro-dollar is a thing
20 years ago was when Al Gore’s influential documentary An Inconvenient Truth first appeared. Almost everyone I knew discussed it, including primary school pupils. Guess what, we do have better tools today than 20 years ago to fight climate change, such as practical and useful electric vehicles to replace CO2-emitting conventional vehicles.
Playing devil's advocate, if you look at the temperature graphs up to now, ignoring the future projections, the temperature has regularly fluctuated to hotter than we have it now (~2C more) and then fallen back (6 less). There must be some stabilizing factors that cause it to do that. Maybe that'll kick in again?
Sometimes this process involves killing off a good portion of the multicellular life on Earth, but sure, maybe that'll kick in again.

(If the former, then how did early humanoids, and many other animals, survive such cold?)
The latter. I suggest reading https://en.wikipedia.org/wiki/Paleoclimatology#Reconstructin...
The later, "−6°C and +2°C relative to" is relative to the mean of 14.

If only there was a clean, nearly limitless source of energy, where the waste for hundreds of years of energy could be stored in less than a square kilometer.
If such a thing existed, we could be sure that environmentalists and leftists would have openly embraced it, rather than nip it at the bud 50 years ago. Because they are Good People™. And we should definitely listen to them now because they Follow The Science™.

The issue with current politics wrt environment is environmentalists and leftists? This feels like a smoker blaming their smoking habit on anti-drug associations not being good enough rather than big tobacco.
CO2 seems very threatening but loss of biodiversity is also a problem, and it has nothing to do with energy...

People may be downvoting you because they think you're not speaking in good faith. But I think this touches on an important issue which is the credibility of politicians when it comes to bringing the science hammer down (in the form of policy). Stuff like the junk science behind those old CA plastic straw policies, the seesawing on Covid prevention and lab-leak denialism, the energy efficient dryers that don't work (this last one is more hearsay to me, and issue of CBA rather than scientific fact perhaps.) I think if politicians can get their shit straight on communicating mature science thoroughly and accurately it could go a long way to getting people to work together.
Surely nothing has ever done wrong with this limitless source of clean energy to give people pause? There's no uninhabitable areas of the Earth due to this?
i'm not sure there are, from a science point of view... From political point of view there are probably only 2 locations in one country... vs a gigantic energy output on planetary scale...
This is 100% uninformed opinion (sorry, HN) but allowing climate action to become a political issue (and a losing political issue at that) was the core mistake the environmental movement made in the 90s and beyond.
If we had created a broad-based constituency for climate action, say, working with industry to build nuclear power or supporting natural gas to displace coal or even funding more conservative think tanks, then we'd be in better shape.
A microcosm of this was local and federal politicians driving Elon Musk to the Republicans. Labor issues and regulatory roadblocks took precedence over supporting Tesla, forcing Musk to seek Trump as an ally. This immediately poisoned Tesla's reputation with liberals and probably set back adoption of EVs in the West.
If climate change is really an existential issue, then we should be willing to compromise on non-existential issues to build a broader coalition. But no one is in the mood for that.
> but allowing climate action to become a political issue
What the hell are you talking about? What?!? This entire issue was a solved problem with a simple carbon tax (which is a conservative leaning policy) and then one party decided their strategy was going to be deny, then delay, then pose it as a fait accompli.
I was pretty damn conservative on a lot of issues when I started college... as it became more and more clear to me -- from taking earth science classes -- that climate change was very obviously happening and that we've known about it since the 1960s and that no serious person trying to suggest that it's not being made worse by human activity, that's when I started to thing that the Republicans were not going to take this issue seriously, ever.
Any centrist or conservative person who takes the issues seriously has no idea what to do because on party just decided to just say "lol, who cares." How in the hell is that environmental movement's fault!?! You look at the UK and environmentalism is not a partisan issue. Here, we have idiots holding snowballs in congress trying to score cheap political points.
I think what you're saying is conservatives should have support climate action (like a carbon tax).
Obviously, they did not, however. The question is what could we (people who care about climate change) have done differently to get broader political support? The problem wasn't getting liberals to support action, it was getting conservatives to support it. Therefore, we needed to do something to appeal to conservatives.
>The question is what could we (people who care about climate change) have done differently to get broader political support.
Literally nothing. Environmentalists can have done literally nothing different. If an entire party is going to take it upon themselves to make "climate change is a hoax" and their constituents are going to go along with it, you just have a large section of the electorate making terrible decision that will make us all poorer.
This isn't something that's a negotiation. The leftist solutions were rejected, the liberal solutions were rejected, the conservative solutions were rejected, and even the right-wing "end our dependency on foreign powers" was rejected. This was a deliberate policy choice by the right, and it was an asinine one.
This is anger and hatred, not logic or strategy. I don’t blame you, honestly. And there are many who feel exactly the same way.
But this is why we won’t stop global warming. Because beating our enemies is more important than saving the planet.
We can be kind, and do our best, and also call a spade a spade:
I don't agree that EVs are worse for the environment than ICE cars. But I don't want to digress. My point isn't about a specific policy (carbon tax sounds reasonable to me, and I agree that it is/was a conservative idea).
My point is about how to accomplish the goal. If we care about climate change, how do we get political agreement? The only way is to find a deal that persuadable liberals and persuadable conservatives can agree on.
I still believe that if the West had built proportionally as many nuclear power plants as France, we would be in much better shape. But environmental activists fought them and here we are.
I think Elon going to the Trump side was another tragedy, mostly because of what it did to EV adoption, but also because it empowered the Republicans who deny climate change and reject solutions. I don't think you can claim that Elon's turn was good for liberals or for climate action.
These are two examples of climate action advocates pushing for policies that made the climate worse.
>My point is about how to accomplish the goal. If we care about climate change, how do we get political agreement? The only way is to find a deal that persuadable liberals and persuadable conservatives can agree on.
You can't. Liberals aren't going to kowtow to the American right (I don't even want to use small "c" conservative here because fighting climate change is a conservative position). At every point along the way it's made sense -- long term -- to fight climate change, and at every point the right has veto power
Look, I've always defended Elon Musk, even after he aligned himself with the hard right. By making EV's "acceptable" to the right, he changed the political alignment on the carbon issue, and he deserves credit there.
Even in blue states, with people assert that they are concerned about climate change we have much of the left states doubling down on sprawl as housing policy. We have people doing everything they can to signal that they care about climate, without being willing to give up their gas stove when given subsidies.
We're not even winning the argument very well with our allies. Politics is hard, even when people are open to being reasonable.
I agree with you in the general but both-siding at the present time when one side is engaging in egregious behavior and lies constantly to make the other side as crazy as they are themselves sounds like an attempt at avoiding accountability.
It's not the few green militant's fault if one side is denying and attacking science, the same way it's not a few crazy leftists' fault if one side is trying to undermine the rule of law and the constitutional order in order to cling to power.
See what I am doing ? I admitting that there are a few nutcases on my side. You ? You are just issuing a blanket defense of everyone on your side (in another comment) including the most egregious (Musk) while pretending to be in the center.
I am tired of all those fake centrists. "Sure he led a conspiracy to overturn the result of an election but on the other hand remember when Hillary called us deplorables ?"
Can't wait for accountability to make a come back
I'm honestly less interested in accountability than in doing something about climate change. If I could solve global warming by giving Elon an extra trillion dollars, I would. If I could solve global warming by giving Trump 4 more unconstitutional years, I probably maybe would (but it would kill me).
My argument is simple:
1. Not enough people support climate action.
2. We've tried demonizing people who don't support climate action and that hasn't worked--it only made them support it less.
3. Therefore, try the opposite: give people an incentive for supporting climate action. That means allying with political opponents, such as Elon or supporters of natural gas, or rich corporations. The broader the base of support for climate action, the easier it is to pass climate action legislation.
what labor issues and regulatory roadblocks? the man is halfway to becoming a trillionaire. if anything there wasn't enough labor legislation and more regulation to spread the wealth a bit
If you care more about preventing Elon from getting richer than getting more EV adoption, then that's exactly what I'm talking about.
If climate change is a major problem, then we should fight it, even if it means Elon gets richer. If you don't think it's a major problem, then mission accomplished.
elon could just as easily be producing EV cars as a single digit billionaire
I'm more than happy to criticize Elon, but seeing as he's only getting richer, I don't think he needs my advice.
But in this post, I'm criticizing people who demonize Tesla to stick it to Elon. That's going to hurt efforts to combat climate change. If you think billionaires getting richer is a bigger problem than climate change, I understand. But that's why global warming is getting worse--because even climate activists would rather fight different battles.
elon/tesla is not the only EV manufacturer, so idk why you are insisting on framing elon/tesla as some kind of climate messiah... in fact elon helped elect the most climate change denialist president in recent history so one might argue elon is actively hurting the global warming fight...
No what's crazy is that something as apolitical as "many scientists specialized in climate have come to the conclusion" was successfully turned into something political thanks to a now well proven denialist playbook. We really need to stop both-siding that kind of thing. One side just said "We should do something about it to save us all" and the other side tried to come up with anything that could make them look evil but in the end what worked was bypassing reason entirely with this new thing called identity politics.
Elon Musk is a half-closeted white supremacist, he was always going to side with Trump. I don't mean that as an insult, this is just what I could gather from his tweets, preoccupations and "roman" salutes.
> If we had created a broad-based constituency for climate action, say, working with industry to build nuclear power or supporting natural gas to displace coal or even funding more conservative think tanks, then we'd be in better shape.
Or those conservatives could have come up with their own version of tackling the issue: nuclear and gas displacing coal. Some of them did I believe, it's just not the version who won in the end. It seems strange to blame the other side for their own "aesthetic" preferences (i.e renewables)
I really don't mean to start a flamewar but your comment gives me the vibe of "I became a nazi because my daughter wanted me to sort my trash" meme or something of the genre where there is no accountability and you are always just reacting to the wrongs of the other side.
I think people who care about climate change should stop doing things that don't work (or even make the problem worse). Demonizing Elon, demonizing nuclear power, demonizing natural gas, forcing people to cut back, supporting de-growth: none of these things have worked to stop climate change. Maybe we should try something different.
Unless, of course, the goal isn't to solve climate change but to demonize Elon. In that case, well done!
I would love to take the bait to talk about how Elon is very good at demonizing himself and does not need anyone to do it for him but I don't care that much about Elon as I care about climate change.
I would like to agree with you but saying "the people who care about that issue are irrational and should be doing X instead of Y" should not be used in defense of "I will deny the issue even exists and attack anyone who tries to alert about the issue"
That was my whole point and you missed it apparently. You just reformulated yours.
I think your argument is that allying with people who deny climate change is not going to fix the climate.
But this reminds me of the Israeli leader who was asked, "How can you sign a treaty with [the PLO, I think], they are your enemy!" And he replied, "You don't sign treaties with friends. You only need them with enemies."
If the political constituency for climate action were large enough, then we would have done something already. So we have to start pulling other people into the coalition.
People who oppose climate action are on a continuum. Some are climate change deniers and cannot be persuaded. But many would absolutely support climate action if the costs to them were low enough. Many more would stop opposing climate action if they got something that they wanted in exchange.
What's fascinating and dismaying to me is that it's obvious that there exists sufficient capital and capability in the west to fix this.
I always wondered if we just lacked the ability to mobilize to solve big problems anymore but now I look at this 7% US GDP being allocated to AI datacentres and I realize that it isn't a lack of ability, it's a lack of desire.
Imagine if we had ram shortages because all the silicon was being diverted towards making solar panels. Imagine if we had copper shortages because it was going to the windings on wind mills. Imagine if all these economic disruptions were just temporary and for a better cause or eliminating carbon emissions and eventually moving to sequestration of carbon.
Instead we get chatbots. And funny picture makers.
Not the same silicon. Wafer fabs make pure crystals. Photovoltaics use polysilicon.
Obviously you mean purified silicon, but, remember silicon is what the Earth has in abundance (yeah I know it’s energy intensive, and there exist such profession as sand prospector.)
Maybe putting sociopaths in charge of the government and the world economy was a bad idea.

The sun expands and gets hotter
Yes, in approx 4 billion years.
I agree that is a concern but I think we should also pay some attention to some of the problems we will be facing in a timescale somewhat shorter than billions of years.

And yet, the only reasonable action to take is to flag this topic and move along with the "humanity has always found a way out, technology will save us. Remember, we were supposed to drown in horse manure!"
Why? Because candidly looking at those risks as a society means deep collective existential dread, which automatically means an immediate civilizational collapse.
So I'm guessing some of our elite is actually ignorant and the other part is willfully shutting the hell up on this subject to let our civilization run on fumes a few more years.
It's unfortunate because a rapid civilizational collapse could give humanity as a species a better chance of survival.

How's that?
An effective way to cut carbon emissions before feedback loops are triggered
Meanwhile all these other AI threads everybody’s worried about losing their jobs
Not realizing we’re gonna go extinct here in the next thousand years unless something solves it
Since humans are incapable of doing this there’s only one possible option: To create something smarter than us and give it the power to solve it because we cannot
> Meanwhile all these other AI threads everybody’s worried about losing their jobs
don't worry
AI will cause both losing your job AND climate change
