A weird title. The content of the paper is summed up as “everyone felt like the climate changed after 2015, the data up to 2023 was inconclusive; we finally have enough to prove it with 95% confidence.” EDIT: The title is weird because it’s generic to the point of being unsearchable. I’m not disputing the facts of the paper.

The title is a fair summary. The paper isn't simply confirming the "climate changed [warmed]" since 2015. The paper is showing the climate warmed the past decade twice as fast as it had between the decades from 1960-2000.

"This 58 indicates that the warming trend has been accelerating from a rate of 0.15 – 0.2 ◦C 59 per decade during 1980-2000, to more than twice that rate [0.4°C] most recently."

What a surprise with all the wars going on, and AI depleting Earth resources, what a change from about the pandemic era when everyone was into paper straws and cups and promising to be a better person, because that is what was going to change anything.

AI is nothing compared to automobiles and heating, construction and shipping. It uses a bunch of energy, but not so much compared to moving yourself around in a car of plane.

A bunch of energy, water and Earth rare materials, nothing really to care about.

Today: this Tomorrow: trillions invested in new technology for simulating human torture accurately at the molecular level, requiring twice the level of all consumer electricity use on the planet. Advocates claim "all use is valid".

Is this a reference to "Torment Nexus"?

It would also work as a jab at Roko's basilisk

China has actually been leading the charge in terms of green energy lately, at least in terms of making solar power equipment more accessible by way of driving down cost. I have no idea however if they're just exporting this to other countries or if they're also pushing renewable energy domestically. From what little I've read on this topic in recent years though they seem to realize that all of that smog is coming f…

China has continued to rapidly increase their use of coal for power generation. Just a few days ago there was an article about them hitting an 18-year high of new coal power installations [1] [1] https://www.forbes.com/sites/katharinabuchholz/2026/02/27/ch...

New coal power installations != increased use of coal for power generation. You have to stop this lie by omission.

Their new coal plants either replace older ones. Or they are left idle. Close to 90% of all their generation growth comes from solar and wind.

They use coal because they have coal. Just like the US uses natural gas and then pats itself on the back for "reducing emissions" by switching from coal to gas. But their current trajectory will see them going to burning very little coal. It's a national security issue for them.

It is also much more likely to use renewable energy. Data centers look at the local energy mix when planning where to put one. (though they are perhaps taking energy that would otherwise be shipped to a different city/state)

Because of how policies are grouped together in many countries (particularly the US), the fight against fascism is necessarily concurrent with the fight against climate change.

In my social circle of liberal people, the reason is despondence.

Climate change has been known for decades now, and despite the alarms and concerns, the current administration is cheerfully, maliciously removing all initiatives in the US to combat it. Attempting to destroy the solar industry and wind power. Rolling back the most common sense environmental controls for public health.

Meanwhile our country has had its place in the world destroyed irrevocably (for at least a generation) and is turning further and further away from a country that cares for its citizens and its freedoms.

People are losing hope, not interest, because climate change and fascism are are more alarming than ever and our government is complicit.

Long standing problems are not being solved.

Was anybody really expecting anything else? The only factor that would matter is if oil producing nations STOP producing oil entirely. Not reduce, not limit, stop. Same with coal and other small contributions. Note: limiting exports, CO2 limits in oil customer states, ... all of that just doesn't matter. And, obviously, this is just not on the table. There is no way these nations will make such a decision because wha…

People are losing their minds at the prospect of oil availability dropping just 20% for a month or two with the closing of the Strait of Hormuz - even just this could collapse the global economy.

So yea, no way is oil stopping or even dipping slightly any time soon.

What small-scale geoengineering are you referring to?

I don't see the US doing anything about global warming regardless of who's in charge. China has won on manufacturing cheap wind/solar energy and is scaling up their cheap EV manufacturing right now. Trump is definitely accelerating China's future dominance by completely forgoing anything related to developing or manufacturing green tech in favor of fossil fuels, but I think both parties would rather get into a confli…

At this point, one possible 50-years projection of outcomes here is that China eventually declares the US an existential threat to humanity's continued existence and deploys economic or military power to stop it unless the US gets its act together on carbon emissions. Can't build those AI datacenters if China has physically embargoed the chips.

That may seem extreme, but the Chinese culture is more collectivist than its Western counterparts and (perhaps unlike the US culture) can recognize a threat as complicated as "This entire nation's set of rules they treat the universe by threatens humanity existentially" even when said nation can't recognize it in themselves. Plus, India is hit hard and fast by climate change in the short run so China already has an ally in their backyard who would support them doing something about polluters.

Basically the oceans are way way way too hot which is melting even the most ancient ice and that can never be undone in our lifetimes (well maybe from a nuclear winter) USA is about to have another El Nino summer which will be scorching from overheating oceans But don't worry, USA is solving the problem by Biden banning cheap electric cars and Trump ending electric subsidies entirely, forcing coal plants to restart

>But don't worry, USA is solving the problem by Biden banning cheap electric cars and Trump ending electric subsidies entirely, forcing coal plants to restart

People really think if they just buy the right products we'll solve this problem. People are really fundamentally unable to solve global warming issues. There are a few fundamental problems:

- Broad, collective action is not possible in just any direction. People can broadly get behind causes that are related to some fundamental human motivation, but generally cannot be guided towards nuanced political topics except via general tribalism and coalitions. (eg: you can go to the moon, but there's only broad support for this in the sense that it has consequences for national pride. You didn't have a whole nation helping the the logistics; you just had broad coalitional support.)

- People think that merely buying the right product will help, but major impacts to climate would require a serious modification in quality of life and material wealth. This will never have broad support. People will always scrape out the most comfort and most material wealth that is possible, and will only allow themselves to be constrained by hard limits. Technology can help here to a degree, but once technology helps, people just advance to the next hard limit. For instance the use of insecticides, industrial fertilizer, and large-scale factory farming just allowed for more population boom. Rather than arriving at a place where where had near infinite abundance, we just ate up the gains with expanded population and luxury products. (sort of how computers don't get faster; once the computer is made faster, the software does more and the actual UI responsiveness just stays in the same place.)

- People would need to intentionally decrease population and find healthy limits with the environment. No living thing does this. If you watch population curves in predators and prey, they occur because the hard limits force starvation and population decline. (ie, if the wolves eat too many deer, then the wolf pups starve, the wolf population declines, and then the deer can rebound.) In other words, nature is not "wise and balanced" but instead the balance is a mere fact of competition and death. The moment we produce an abundance, we use up that abundance. This may not be true in the case of some individuals, but broadly this is true for any population.

- No political body, even an authoritarian regime could force these things. People would revolt. Authoritarians themselves often get into power by promising abundance they can never actually deliver on. No authoritarian has gained power by promising to reduce abundance and material wealth.
