China is building clean energy for a good chunk of the world, including itself.
A better question may be: What is the US going to do to make up for its historical emissions? The US got wealthy by creating far more emissions than China, and all those historical emissions are now a problem for the rest of the world.
If people in the US try to turn climate action into a blame game, it will end very very poorly for the US.
Pure fantasy. What will happen to the US and who will do it to us?
If the US starts trying to force other countries into climate action without taking into account its own contributions, the US will likely cut out of the global economy, and become far poorer as the rest of the world surpasses its wealth through vigorous trade.
The US was the sole remaining superpower, but has recently decided to only occupy a much weaker position with a mere "sphere of influence" and ceding leadership in other parts of the world to others. The US is signalling to allies in Europe that it will no longer lead, that the prior world is over and the US is bugging out, meaning Europe will gain far more influence.
The more that the US attacks others without providing any leadership, the less that the US will be able to take from the world. Up until recently, the US's position of massive economic strength was largely due to it's dominant position among nations and the goodwill that others had towards it. Turning the climate problem into a blame game on other countries would further weaken the US's position and options.
You seem to think these solid critiques about the inherent weakness of Trump are somehow mere partisanship, rather than the actual unwinding of US leadership around the world.
I'm not part of global academia, I'm just a consumer of news that is willing to listen to things outside of a partisan bubble. The world is shifting away from the US, to the US's detriment. We have an exceptionally weak president who acts like what a weak person imagines a strong person is like, and it's scaring off all our allies.
> In a way it’s understandable because you all seem to believe in your “right” to pick winners and losers. The world doesn’t actually work that way.
I do not know whatyou mean by this, you think I'm picking winners and losers? The US is picking winners and losers? Global academia is picking?Picking either antecedent does not allow me to find any meaning in your sentence.
While China is still very reliant on fossil-fuels, and particularly dirty coal, they're at the same time working on dominating the post-fossil age at astonishing speed. After they already dominate solar and batteries, they're working on doing the same for a number of other future green industries. They are already dominating future technologies like Green Methanol that most people in Europe or the US have never heard of.
It's logical to start with the king of greenhouse emissions if you want to stop global warming.
But per capita is more informative when thinking about policy for curbing emissions, which is how we actually change our effect on the climate.
If China were to split into 10 countries each emitting 10% of what they do now it'd be the exact same emissions, but according to you it would be much better.
Similarly if the EU would become one country, that country would be high up on the list, much higher than member countries now! Oh no!
Looking at per capita emissions is much more fair.
Anyway, China's emissions are falling since last year ( https://www.carbonbrief.org/analysis-chinas-co2-emissions-ha... ). What's the US doing?
But policy is where real change needs to be made, and the effects of policy still scale with population in most cases.
Also, you don’t want all the low-population countries to each start contributing as much to global warming as the US.
China's emissions were 10 billion tons CO2 in 2017 and have increased every single year to 12.29 billion tons CO2 in 2024. Meanwhile, US decreased from 5.22 to 4.9 in the same time
US emissions icreased by 2.5% https://rhg.com/research/us-greenhouse-gas-emissions-2025/
China's emmisions have decreased by <1% https://e360.yale.edu/digest/china-emissions-decline
China has only produced significant CO2/capita in the last decade. The US and Europe are responsible for the accumulated GHG that have gotten us into the current mess. We blew nearly the entire CO2 "budget" for keeping us under 2C of warming, just by ourselves, so it's kinda odd to be pointing fingers at the foreigners who are just now halfway catching up to what we're emitting now.

PRC solar power production last year conservatively will diplace ~45 billion barrels of oil, or 10%-20% more than total global consumption per year. It's just retarded eco accounting that attributes emissions to renewable manufacturers while fossil exporters don't get any penalties for extracting emissions.
Every year of PRC solar prevents doubling of oil, basically they're like the only significant country whose net contribution is negative for how much carbon sinks they manufacture. So the answer for US+co is obviously stop exporting oil and lng, and start exporting renewables.
I hope we steal their playbook.
That’s a real problem, because China, and all the poor countries in Asia and Africa aren’t going to stop increasing their CO2 output per capita until they reach western standards of living.
So: atmospheric climate science directly falls under NASA's responsibilities.

We’ve known about the mechanisms of CO2 leading to atmospheric warming since the 19th century.
We know humans are adding CO2 to the atmosphere.
We observe higher CO2 and warmer temps
The evidence isn’t that complicated.
The science behind it really got going in the 1890s, with Arrhenius' paper predicting climate sensitivity to CO2. That was bounced back and forth with rebuttals and counter-rebuttals until about 1950. Major debate points were how much role water vapor played, how this varied with temperature/altitude/pressure. (You can trace each part of the argument if you're so inclined; there's lots of neat science in there. The concept of "pressure broadening" was my favorite; it explores how spectral bands change with pressure).
Around 1950, the science started settling out. Spectrometers had improved, we had clearer view that CO2 and H2O don't fully overlap in their spectra bands through the atmosphere, and we had the computing to do better calculations. By the 1970s, we were getting ice core data showing that the world had gone through huge temperature swings, and how this changed with CO2. Enough data had accumulated that a consensus was forming. In the 1980s, scientists were now concerned enough to form a large body to inform policymakers on this issue (IPCC; 1988). And in the 40 years since then, we've mostly sat on our hands, even as the science just gets clearer and clearer.
I share all this long history to explain that the science went through nearly a century of rigorous debate even before politicians got involved. This a scientific issue, not a political one. And I'm glossing over 99.9999% of the detail here. There was an extensive literature debate between the scientists, hashing out any point you can think of. You just have to go to your local uni library and start reading.
TL;DR: saying that global warming is debunked is about as incorrect as saying that the Earth is flat. We have extensive evidence showing otherwise.
