Is this a reference to "Torment Nexus"?

While I'm sure that subconsciously influenced what I wrote, it was more a general jab at the sentiment that negative externalities can always be justified so long as a technology has users who prefer to use it.

Ah, I thought you were just referring to the decades-long use of the most massive supercomputers to simulate nuclear arsenal maintenance and explosions (maybe literally at the molecular/atomic/sub-atomic level).

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.

Yes. The obsession with demonizing AI/data centre loads seems to be a deliberate distraction from the much, much larger carbon loads of the economy at large relative to which IT power consumption is a tiny proportion.

When the oil in your frying pan is smoking, adding a tiny bit more heat may be unwise.

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.

"inconclusive" only regarding the significant acceleration. The warming part wasn't in question. The actual abstract reads: "Recent record-hot years have caused a discussion whether global warming has accelerated, but previous analysis found that acceleration has not yet reached a 95% confidence level given the natural temperature variability. Here we account for the influence of three main natural variability factor…

Man, I get definition-lawyered a lot on HN but this is something special.

Nothing will change until developed rich countries are starting to hurt.

And I don't think it's going to hurt enough in 10 or 20 years.

The pain will come slowly, people won't see it.

It's like going back to the middle age so slowly, that the population don't realize or feel it.

And honestly, wars and trump are making climate concerns so difficult to think about.

As an observation, global warming has completely disappeared as social concern in the last few years. Great that someone is still publishing research, but it seems like being a climate scientist has gone from hottest field to nobody cares.

I think a lot of people have lost faith in the ability of the world to come all together and make the necessary sacrifices to make a difference. Especially when some parts of the world are in competition with each other and not making these sacrifices allows them an edge. Also another group of people have realized they are not willing to forgo all their petty and unnecessary comforts nor are they willing to pay any p…

"People aren't willing to pay price increases" is interesting. Of course that's what they say when you ask them directly. Yet everyone is currently paying massive price increases as a result of covid-era money printing. I'm not saying you're wrong necessarily but what it shows it that it has been possible in very recent times that a collecive decision was made which increased general prices for everyone.

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…

The one thing the US could do to combat global warming is dropping the tariffs on chinese renewables. That's something that could possibly go through a regular spending bill.

Power companies in the US are already deploying renewables pretty quickly without incentive. If the tariffs are dropped that'd further incentivize build out.

What should be done is carbon taxes and subsidies, but that's not likely to be done. And since that's not going to happen, economics is what will drive transition.

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...

It is deceptive to compare coal % of power generation, because China specifically substitutes coal for gas because they have none of that (and no reliable source). This also means those coal plants run at lower/decreasing utilization because a big part of their role is to provide dispatchability. So for China you have 55% coal and 3% gas while the US uses 16% coal and 40% gas for electrical power.

If you compare numbers, you will also find that lower per-capita consumption more than compensates for currently still higher CO2 intensity of chinese electricity (3000kWh/person * 0.5kgCo2/kWh for China vs 5500kWh/person * 0.35kgCo2/kWh, i.e. 1.5 vs 1.9 tons of Co2/year/person from electricity for China vs the US).
