Why so blatantly lean into Jevans paradox? In this case, there is no ceiling on global emissions. If one country reduces to zero there would absolutely be less emissions than if they hadn't. There's no incentive for China and India to pick up the slack and create more pollution just to cover what the US stopped making.

It's not real. Even if it's real it doesn't matter what I do. Any more lies?

Sorry I don't follow your point here. What are you trying to say?

FWIW my personal assessment is that this acceleration is both real and largely out of our control. Models in the past did not attempt to account for non-anthropogenic carbon emissions, but as we experience further warming, most especially in the Arctic, feedback loops and tipping points mean that this (carbon emissions caused by “natural” processes) are becoming more evident. This is especially sensitive because a la…

> Oh and roughly 65M of sea level rise as the planet shifts to a snow/ice-free mode

65M seems a lot bigger than the 3.6mm/year rise we are seeing today (with +1.5C in warming already happening). Where did you read that we will get 65M of sea level rise with 1.5-2.5C more warming?

Would someone like to explain why the Chinese (if as you say produce 30-35% of global emissions) don't appear to see a problem or at least if alluding to it as they do, fail to do much about it as major contributors of emissions? And then of course there are the countries proud of a relative lack of emissions who are merely exporting the problem to somewhere else, often enough, China.

Yes, they're still burning coal and gas but China are making huge strides in non CO2 intensive electricity generation China are the reason solar has become so affordable for the rest of the world

The latest major IEA estimate says China’s CO₂ emissions reached 12.6 Gt in 2023, up 4.7% from 2022.

On the other hand U.S. CO₂ emissions decreased slightly between 2022 and 2023. About 2–3% (from 4.79 to 4.68 Gt)

I just do not understand how we can claim any kind of progress here.

I don't think that's fair to say; the USA's CO2 emissions per capita are roughly 150% of China's, and the average Canadian emits more than 7x as much as an Indian citizen. The entire EU produces only about half of the USA's total emissions, despite having a population of over 100 million more people.

Fair? Maybe not, but IMO it doesn't matter. The only thing that matters is gross emissions. The effects of a warming planet will not be fair. We should be looking to reduce/eliminate emissions wherever they are happening.

> The only thing that matters is gross emissions

Which is why, unless you can come up with a good argument that some people have some kind of divine or natural right to a bigger share of whatever global emissions budget we decide we need to stick to, per capita is the correct way to compare countries.

What about solar shades? Seems like a relatively quick and easy way to regulate solar input. It's nice too because you can quickly remove it if necessary.

What percentage of the 128-million-square-km cross-sectional area of the earth are you proposing to shade?

kinda obvious, the wealthy parts?

Ironically, those still unconvinced of the human influence on climate change seem to be the sort that would trust the basement randos more than they would reputable scientists

Theres a mistrust of government and the establishment. Not saying fringe is better but the behavior of govts, corruption and influence by rich donors doesn't help

It also doesn’t help that anyone with few scruples and a desire to make a buck can quickly monetize screaming about how up is down on YouTube

No one thinks only corporations have to sacrifice; they do think that it's folly to ask individual members of society, who on average contribute the smallest overall proportion to global warming, to sacrifice while corporations continue to squander away our natural resources. And the pareto principle agrees.

No, that's insufficient. Yes, corporations that cause the most warming will need to be curtailed if we're to survive. But those corporations are in the act externalizing costs. Once you force them to internalize those costs, the visible costs to consumers will increase, meaning less consumption overall. If you can't convince those consumers that less consumption is a good thing if it's in the service of saving the bi…

I think the problem may be that consumerism is the only thing most people have left. Capitalism has already comodified culture, ground workers down to replacable cogs, and put home ownership out of reach. I think its reasonable for people to demand that some of those things be given back in exchange for abandoning consumerism.

I believe that as soon as nuclear fusion becomes operational (and perhaps AI could be of great help in this regard in the next 5 years), all the carbon storage methods (efficient and otherwise) studied so far could be immediately put into action. In addition to the immediate reduction in the use of fossil fuels for energy production, the scenario could be completely changed in 10 years, water could be desalinated, de…

> The question is whether we will get there before it's too late... and perhaps AI is the answer?

I won't touch "free and unlimited energy", but is there even evidence that AI produces more energy than it uses? Produces any at all?

"But the economy" is an out-of-date framing. The cost of renewables has been plummeting for well over a decade. New renewables are now cheaper than new fossil fuel plants in most of the world, and in many regions they're already competitive with or cheaper than simply running existing fossil fuel infrastructure. As modern wars in Ukraine and now Iran are increasingly demonstrating, they are not only cost effective bu…

In principle, you are right. Cheaper than coal renewables are winning. Don't forget though, that fighter jets can't operate on batteries.

That’s a red herring. It’s not worth mentioning.
