The only hope now is exponential growth of (solar and wind)+batteries making other sources uneconomic. This seems to be slowly happening, so I hope we hit the exponential curve soon and we're there quicker than we expect.
This only stops it.
Then, to fix it, we'll need a massive Direct Air Capture industry that will have to operate for a century, and probably past that so we can hit and maintain a CO2 level of 250ppm.
We had the means to avoid this (strict vegan diets, ground based mass transit, dense development & re-wilding, energy transition) but people made money doing the opposite. And more people made money sabotaging solar+battery pricing in the US.
So we get to watch the world burn down around us.
"Making money" is the incentive system of society. Technology has now aligned society's incentive systems to promote climate action.
People who refused to acknowledge the reality of human society, refused to acknowledge that the profit system exists whether they want it to or not, are responsible for focusing action on ineffective means of change.
And vegan diets would make a big dent, look up agricultural sector emissions, look up beef emissions and methane from their burps. It’s a major factor after transport and electricity.
Then explain voluntary work or all the people risking their lives for other people they don’t even know.
Human society existed before money.
And nobody said that a vegan diet would have stopped climates change, they said strict vegan diets, ground based mass transit, dense development & re-wilding, energy transition.
Just picking one and say that would help is a nasty tactic.
It’s like saying you need water, food and sleep to live and you say, nope, water alone doesn’t keep you alive.
The reality is, consuming and producing less works but it’s harder then keep going and hope for a technical solution.
Same with being overweight, more sports, less food works but doesn’t make fun.

>Livestock production accounts for 14-18 percent of global greenhouse gas emissions, including 32 percent of methane gas emissions worldwide.
14-18% seems like a fairly significant chunk, no? and what if we just started with not eating beef, all of us, especially the USA? that'd cut down the emissions by quite a large bit
I also feel like the idea that technology will save us can only exist if you're fully ignorant of the sheer amount of money poured into lobbying by various industries into deregulation (like, for eg, the beef industry: https://www.ucs.org/about/news/agribusiness-industry-lobbyin... or Taylor Farms https://www.wired.com/story/diarrhea-outbreak-taylor-farms-m...)
not to mention the abandonment by state energy companies like Georgia Power of their solar/renewable goals and full buy-in to building yet more gas turbines in order to attract hyperscale data centers. I was part of some organizing against this in my city: https://atlpresscollective.com/2025/12/18/public-service-com...
just look at the funding for renewable R&D in the past few years - the reason we have the market we do now is that huge spike (thanks, Obama) in 2009 that drove down the cost of manufacturing and drove up conversion efficiency. that much investment into the renewables sector hasn't been the same since, especially now: https://www.theinvadingsea.com/2025/11/05/fossil-fuels-oil-c...
Thank you for writing that, because I think it is the key point. It's very easy to blame "decrepit old men" because that makes it someone else's fault - and I get it, as I think that there are a bunch of decrepit old men that deserve a lot of blame.
But democratic societies (and even authoritarian ones that are still somewhat subject to mass unrest) were never going to accept large negative impacts for a consequence that was not immediate and in your face. Like you put it, just go around and ask your average Joe or Jane if they would vote for any candidate who demanded strict vegan diets (or heck, even a lot of the other things on GP's list). You're fooling yourself if you think it's only decrepit old men who don't want that stuff.
And regarding GP's comment that "And more people made money sabotaging solar+battery pricing in the US." Yes, there are some people trying to sabotage this to make money for themselves, but it will not take them too long to fail miserably precisely because the economics are not in their favor. Just look at Texas - not exactly a place known for its love of vegan diets, among other things - and solar, wind and now batteries are now a huge portion of the energy mix and growing fast precisely because it's economical.
no, it has not
Strict vegan diets would objectively massively help reduce climate change.
This personal belief is grounded on an assumption that all mankind follows a neoliberal or even libertarian economic model.
Back to reality, west Europe is firmly a social democracy where states impose behavior through law, regulation, and policy, which is topped by a federal system that coordinates policies. Countries such as China are totalitarian with a centrally managed economy that's guided by N-year strategic plans.
Technology is the only option in constant system, but with nothing happening, the system won't remain constant for long, and sacrifices will have to be made, not by choice.
The developed countries have so much land, water, resources that they will adapt although inequality within will be an issue and tbh at this point there is never any thought given to the wider world, which if one things about honestly never was.
I admire anyone and everyone who wants to be a vegetarian/vegan. Expecting the rest of the world to follow suit is a fools errand.
People are meat eaters. If I was to run a campaign to keep the green movement unpopular, I’d promote enforced veganism as one of its core ideas.
I'm not saying degrowth is feasible, mind you. I agree that it probably isn't. But the fact we can't do something doesn't mean the alternatives must be good. It might just mean we're cooked.
This right here, the absolutely preposterous idea that giving up kids is somehow climate action, is exactly the nonsense that a climate activist should never tolerate.
You think climate action is everybody stopping having children?! You think extinction of the human race is the only option?!
"Of course not!" You say, so clearly we must have some children. But how many? If we drastically reduce our population, we will continue with the same broken systems, same energy systems, etc.
Only by keeping society running do we have the energy to switch our society's engine to zero carbon energy sources.
It's insulting to tell people not to have children, it's not realistic, but worst of all, it's not a climate solution to not have children.
"Don't have kids" is just Malthusian nonsense from a prior environmental era, uncritical thinking, pure slop.
And it greatly harms actual climate action when this extremely stupid idea gets associated with the climate movement. Stop. Just stop.
Mass transit and dense development are potentially doable, but at this point the suburban sprawl + car model has been popular in the US for decades and it would feel like a downgrade for many people to live in smaller places in more heavily urbanized environments. I think that many Americans don't even have a clear idea of what it would look like to raise kids in a multi-story residential building in a city without it seeming like poverty.
Also, in some parts of the US, mass transit and dense urban living run into the problem of anti-social behavior including street violence. Many of the people in the US who care the most about stopping climate change also oppose the kind of intensive policing that would be required to keep crazy dangerous people off buses and clean up troubled neighborhoods enough that the average person would feel safe living there. Violent crime rates have largely been going down since the early 90s, but are still much higher than in Europe. One of the reasons for the high rates, through definitely not the only reason, is the availability of guns, but getting US right-wingers to accept gun restrictions is probably even less probable than getting US left-wingers to accept major crackdowns on street crime.
If we need to make such drastic changes to human consumption, have people considered if we have a overpopulation problem?
Thus, technology-will-save-us is the rational choice. Drill all the oil, build the biggest datacenters and speedrun to fusion before the collapse so we can sequester the carbon back into the ground and still have energy left to run Haber-Bosch, ideally with hydrolysis instead of natgas.
Disclaimer: I used to be heavily in the sustainability camp in my younger years
Relying mostly on technology that doesn't yet exist seems absurd to me. We have an incredibly hard problem to solve and maybe a narrow window of action, we should use all the tools we have at our disposal: rapid deployment of available solutions, sustained research into better ones, adoption of more frugal lifestyles, development of alternative sociological, political and economical frameworks.
sabotage achieved
You say it's for the benefit of "decrepit old men," but the fact is that more and more of the globe is being lifted out of poverty and living more comfortably than ever before. The unfortunate fact is that global warming is an unstoppable force now, humans would have to go extinct for it to waiver.
I'm not saying we should do nothing, but I am saying that your framing is exactly why no one listens to global warming advocacy. We are powerless against it, not because of governments, but because people are living better and no one is going to sacrifice that; and even if they did the math doesn't add up to reverse course. The people that say we should all be sacrificing are often the richest among us that don't even know what sacrifice entails, contrary to your point.
I hope you are wrong that nothing requiring sacrifice can ever be accomplished.
This is ignoring that _not_ solving global warming will make everyone's life worse regardless.
And individual action has switched to just holding governments and industry responsible. Which basically amounts to giving up.
"Welp, just gonna buy this truck, enjoy my burgers, set the AC at 68 and fly on all vacations this year because it's nothing compared to Big Oil."
https://www.theguardian.com/environment/2025/sep/27/meat-gas...
https://ourworldindata.org/food-choice-vs-eating-local
Replacing those with basically any other meat (pig, chicken, fish) would make a huge difference already. And it's far more realistic than no meat. Indirect demand destruction (from cost increase) through carbon credits or something like that in the future?
Though, as always, we can and really should do both.
Big oil isn't going to kick down your door when you buy an EV and switch to solar. There is no rancher in the grocery aisle slipping steaks in your cart.
Individuals purchase products from companies, driving that demand. Then are absolutely unwilling to make even the tiniest, temporary sacrifices to demand those companies reduce those externalities.
Hell, half of these individuals don't even both to vote. That's straight-up the bare minimum participation trophy level of effort.
So yes, Governments share by far most of the blame for this. A specific individual is not going to change their life stye unless forced to, that is human nature.
Instead we have had governments in the US being too afraid to do the right thing. The only possible US President that was willing to make big changes climate wise had his election stolen by the Supreme Court in the year 2000.
So here we are still with no politician willing to really force changes on people's life style in the "first world". All they are doing is trying to keep the price of oil low.
One final thing, in the US, if you try to use electricity from all renewals, the price is much higher. And in some cases electricity you receive is still generated from fossil fuels.
We can quibble about edge effects like "induced demand", but by and large, people just love cheap energy, cheap calories, and can shift the moral burden by playing "not my responsibility" games.
Don’t take this as an argument against these technologies. It’s a huge win to not be increasing the CO2 concentration in the atmosphere by burning fossil fuels.
"Small reduction in land surface albedo due to solar panel expansion worldwide"
https://www.nature.com/articles/s43247-024-01619-w
If you download the supplementary information PDF, figure 19 shows a plot of GHG payback times by site. The most common time is about 1 month. The greatest time they found was about 9 months. These times go down as solar panel efficiencies continue to creep upward, because solar panels in 2026 don't have lower albedo than in 2024, but they do have better light-to-electricity conversion efficiency.
As for making the earth less reflective with PV panels... yes, you are right and most of that absorbed solar energy directly contributes to heating the earth because PV panels aren't anywhere near 100% efficient in converting it to electricity, but even the part that is converted to electricity will become heat again in the end, like when it powers AI data centers. (If PV was 100% efficient, then the lack of reflection wouldn't directly do any heating, the heating would all happen when the electricity is used.)
For now that isn't a big concern because the greenhouse gases our civilization is releasing into the atmosphere do so much more heating than all our use of energy, but if we do become 100% renewable and survive that particular danger, then by Jevons' paradox we'll soon be using 10x to 100x more "clean" energy and be heating the earth all the same again.
Then note that a higher temperatures will increase the radiative losses.
100x heat release and it's still about 1% of solar gain.
Every unit of fossil fuel we burn makes the earth permanently less reflective (or at least something on the order of 100 years). You could compare a 1GW solar array (for its lifetime) to a 1GW coal plant running for x days, though I don't have the value of x.
I am not very surprised, since the people voted for the "drill baby drill" president?
I wouldn't classify that as anemic.
The 2020s climate action movement in the US (and the UK) was disastrous in their strategy, action, and outcomes. I was there, I followed along because it seemed like the best way to get climate action, but things like Sunrise and XR at their very best did nothing. They focused on all the wrong people, focused on all the wrong levers. They turned allies into enemies, by "protesting" tech companies that were at the forefront of real action. They refused to acknowledge the massive effects of technology change, and the need for quick adoption, and the huge money saving nature of the solution.
I have zero patience for those attitudes now, the difference between a degrowther and a climate change denying politician are minimal in effect, and the effects are all that matter now.
This is precisely the opposite of the disastrous 2020s action, which had no concrete policy demands, which leaned into the culture war. They ceded the ground to the right wing, who does that sort of culture war much better, as they have focused their efforts on it for so long.
With culture war, no policy changes. The fight takes place in vibes.
We need policy, execution in concrete changes of physical things in the real world. That's where Sunrise and XR failed.
Removing CO2 from seawater would be more efficient because some of the work is already done for you, and you'd be de-acidifying the ocean long term.
Land only slightly beats the ocean, like a 53-47 split or something, and trees are only part of the primary production on land: https://en.wikipedia.org/wiki/Primary_production
This is also why you sometimes see startups pumping green goo through plastic pipes for home-scale solar biofuel systems.
We need massive bounty programs that pay out irrespective of nationality for every possible kind of improvement and gain to carbon capture technology if we want to prevent 90% of all land on Earth between 30°N and 30°S from slowly turning into copies of the uninhabitable stretches of the Middle East.

Notice which countries are going down. Notice which countries are going up.
I didn't go into the study, but looking at all the little text blurbs about the numbers, I don't see anything about if a US citizen purchasing a product that's made in China counts as US emission, as it obviously should.
Still, if you want to have your new iPhone 18/19/20 pro ultra max, it has to be produced somewhere..
So maybe it's time to rethink this and get back to the drawing board..
And it's FAR from hopeless. Again, global warming is obviously happening. But the amount of adapting and reacting to it is virtually nil. Installing AC. Tree cover in every city. Start serious discussions on what level of risk we want with geoengineering.
Because yes, there absolutely is an acceptable risk level with geoengineering. Planting trees is that. Carbon capture is also that. And better and more effective tech will definitely be available.
But we're in a social climate where I don't even dare write down examples of what those more effective methods would be, because if you're not luddite enough you're the enemy.
Maybe try giving it a second pass?
Because for most countries (and certainly for the largest oil producer in the world, Russia), global warming saves greatly on winter fuel use and increases agricultural harvests AND allows them to keep their population happy (because nothing keeps populations calm like cheap fuel/energy). That is the net effect, today.
Because for a lot of countries that really are the beneficiaries of causing global warming, ie. the oil producer countries, Russia, Saudi Arabia, US, Venezuela, Norway, and many small ones Azerbeidjan, causing global warming (ie. selling fossil fuels) is often the only reason they have an economy (mostly all except the US). So they demand a LOT of money, for free, to stop it. And nobody will pay that.
The last argument even goes for countries that are not direct oil or coal producers, like India or China but it's effectively the same argument (China runs on coal, and the country works on exports. Without energy no exports, so their coal usage is still increasing. Ie. same argument as above, they only have an economy because they're causing global warming, just more indirectly than Saudi Arabia)
Because WW2 was won with oil, and so countries that either want to start a war ("or fear they'll be the target/victims of the next big war") want access to oil. This argument goes especially for China, who fear they'll be targeted/"victimized" when they attack half of Asia starting with Taiwan and to a lesser extent for India (who feel they'll be at war with Pakistan, and Bangladesh whether they want to or not, and maybe China too) and even for EU countries (ie. for the ones that matter, France and Germany)
Look up China's oil reserves. You'll be collecting your jaw from the floor, I promise.
Summary: because most governments care about various things ... and not at all about people, about you. Mostly governments not even about their own people and certainly not about the climate where you live. They have a million concerns, a lot of which require fossil fuels, and for the people that compose those governments, climate change just doesn't matter.
Plus, if they can just do nothing, you still have to solve global warming. So doing nothing, aside from being very profitable, is also a great tactic to get you to fix it.
I feel that way of looking at it makes changing impossible. It's our own behaviours and systems that will have to change. There's nothing to fight here, the answer instead lies in collaboration.
Collaboration implies we are all on the same side. Reality suggests some people have made it their business to be on the wrong side.
- COVID pandemics: everybody at home, less traveling, massive economic reset and massive capitals injected (EU recovery funding, quantitative easing)
- Russian attack on Ucraine, stopping a big chunk of gas and petrol to Europe
- Strait of Hormuz, also chocking oil coming to the rest of the world
We could have said: "oh, let's swap those energy sources to renewables", "oh, let's bind those capitals to de-carbonization projects", "oh, let's plant trees", "oh, let's stop deforestation". A lot of things could have been said and done. But, well, a certain degree of coordinated intelligence is too much to ask.
At this point I have lost all hopes, whatever comes, we have asked for it.
El Niño this year is going to be especially crazy, worst in human history by a large margin looks like. I'm putting together El Niño Climate Week to work on averting the worst impacts. It's a good opportunity to move the conversation forward about how our climate is changing very quickly.

My projects tend to be pretty good schelling points for people that like to take action, in case you're finding the comments here frustrating ("I'm not surprised", "we just need to X", "we're doomed", "it will be fine", etc etc etc)
Something other developing nations would need growth for to achieve.
So that's kinda interesting, because degrowth is seen as this conceptual antagonist to the people letting the global south burn, but they both are letting them down - just marginally differently.
It is, and they are. We keep hitting record X Y and Z temperatures, cyclones, etc, and they're on the brig shouting "it ain't global warming you morons"
1. Emitting fewer greenhouse gasses. Need to do that more than ever, but we are now in overshoot so…
2. Actively remove greenhouse gasses from atmosphere. Will need to do that, but land use and dirty energy trends away from net negative. Also, it’s a 100 year project once started.
3. Shade Earth. Not regions, The whole globe. There are two ways to do that:
a. Stratospheric aerosols b. Planetary sunshades in space, at Sun-Earth L1.
That’s the whole solution space, conceptually. As long as we continue to fail within that space, we will suffer compounding effects of unmitigated climate change.
This will not address the acidification of the oceans which is very bad but something is better than nothing.
Carbon capture is way too slow to work. It’s a rounding error.
The West knows that it will manage even with more than that, but it also knows that not everyone will.
Jury's still out on whether the neglect is just due to apathy or because it might be beneficial. Only time will tell.
Systems and politics are not that. Not at all. They're cold, calculating and fundamentally sociopathic.
A more fitting analogy I think would be "Yes we were bought by a bigger company, but trust us, there will be no changes". Of course the buyout came with exact plans on who to lay off when, but panic would be bad for business.
We won't slow climate change. We can build resilience to the effects, and we have good incentives to do so. But we'll keep burning fossil fuels for a very long time.

I remember seeing just a few years back, a Greenpeace postlet moaning about dangerous nuclear energy
I think it's pretty clear that nothing meaningful will be done because there's no shock value to entertain the "empaths" like there is with war and other stuff
It is hard looking at Vogtle, Virgil C. Summer, Olkiluoto 3, Flamanville 3, Hinkley Point C, Hanhikivi and the countless cancelled projects and think: ”That’s what I want some more of!!”
The entire Western world (with the exception of France) pretty much stopped building nuclear power plants 40 years ago, because of a single accident that by its most pessimistic estimates killed fewer people in total than coal emissions kill every 3 days. It’s madness.
In hindsight it’s much easier to blame the accidents rather than face the structural problems nuclear power has.
Which has only been exacerbated by renewables and storage disrupting the global energy markets, forcing ”baseload” plants to become peakers. Against their will.
Oh yeah, would love to see the resilience that would have prevented the Nepalese disaster
I need to say WTF, the way out is to stop pumping CO2 into the atmosphere. That means stop using fossil fuels. How many times does this need to be said ? Already it probably has been said millions of times.
I just hate this post-Trump, post-Covid, post-Russia-Ukraine-war world. I don’t know what the trigger was, but there must have been a point where things just went to shit. And here we are: an increasingly ultra-capitalistic dystopia where wealth seems to be the only thing that matters.
ssearyus: At the risk of being immediately downvoted, let me point out that a 250ppm CO2 level is borderline disastrous for plant life -- at 180ppm, plants would starve globally. The increased CO2 levels in recent years (slightly added to by human activities) is immensely helpful for drought-resistance, as stomata do not then need to open as much to get sufficient CO2 with the result that they transpire less water. The above, and the fact the by far the most important GHG in the atmosphere is water vapor (CO2 is comparatively a rounding error) should give reasonable people pause for thought.
My response: I think there's something you're trying to say, but it doesn't come through clearly in these many points.
- 250ppm is not disastrous for plant life. That's around preindustrial levels of CO2 (280ppm) and plants did just fine
- What do you mean by "starve" here regarding 180ppm?
- And why are you talking about 250ppm and 180ppm specifically? No one is talking about 250ppm or 180ppm as targets (or maybe you are?)
- Water vapor is indeed a greenhouse gas, and contributes to warming. But it's best thought as an accelerant. Warmer temperatures bring more water vapor bring higher temperatures, bring more water vapor etc etc. The rise of carbon dioxide in the atmosphere is so important because it trigger in many ways a feedback loop, one of which is rise in water vapor as a greenhouse gas. The feedback loop caused by temperature/water vapor is one of the reasons we need to be very careful with our human-made emissions.
- "CO2 is comparatively a rounding error": Whether by mass or volume, CO2 is not a rounding error by comparison to water vapor. There's roughly 4 to 6 times the amount of water vapor as CO2. I wouldn't call 25% a rounding error. Maybe there's something I missed here.
- And when you say water vapor is "by far the most important GHG in the atmosphere", does that mean you're working on lowering water vapor levels in the atmosphere? Or what are you working on regarding solving for this? Maybe something with airplane cloud formation trapping heat?
From a warming perspective, it's utter madness to let this build-out proceed unimpeded. New data centres should be required to be net-zero at power-up. Unfortunately, it's a race and the U.S. side of it has an administration that is actively rolling back policies that fight climate change.

I wouldn't necessarily focus on it, but it's something good for your mental model of how to solve the challenge.
The reason I say I wouldn't focus on it is I'm coming around to the idea that "carbon footprint" is effectively a marketing campaign brought on by oil companies to have us focus our individual power where it has the lowest leverage - sorting trash, our own individual emissions, etc, Instead of mobilizing hundreds, thousands, millions, and billions of people to change policy and technology.

Regardless of that, I agree that making useful policy changes is important, replacing some plastic straws won't make a huge change, but getting rid of coal will.

Go and get depressed... or maybe go and eat your Brazilian meat burger, drive your SUV and book your flight to Hawaii, it won't last long.
Do you have any specific, actionable proposals to solve this problem that don’t rely on us magically solving the collective action problem?
A vague sense that “we can do it if we just try!” is no better than what you’re decrying.
With regards to concrete solutions, we could stop pretending that financial optimization and private equity is anything other than looting at scale, we could stop pretending that it’s the god-given destiny of every imaginable product to get shittier and require more rapid disposal and replacement, we could stop imagining that Jeff Bezos shooting people into space is the sign of a functioning economy, but very very directly, we could start actually taxing people and corporations for the long-term effects of their actions, we could prosecute people who attempt to buy, bribe, or market their way past social issues, and we could start incorporating the full cost of, eg, offsetting category 5 hurricanes and large scale droughts or heatwaves in our calculations of the benefits of our modern supply chains and globalized markets. All of those things would be fine starts to drive policy in the directions we want. All of them run afoul of the current winners of the current systems, which is why they’ve been tarred as the unrealistic fantasies of people who aren’t interested in spending the rest of their lives in hermetically-sealed air conditioned boxes so Sam Altman and Elon Musk don’t have to go to therapy.
The Industrial party of the last 2 centuries is over. We should love the trees, the animals, the land and leave ASAP from the cities.
Unfortunately, the plutocracy has different plans.
billionaires, boomers, decrepit old men, and o&g industry have fucked future generations and humanity.
What's needed now is something like a "carbon wave", where you evaluate your impact by how quickly you move the entire world forward.
There's a new book on this to that just arrived to me last week: https://www.barnesandnoble.com/w/the-carbon-wave-leah-c-stok...
