Major reversal in ocean circulation detected in the Southern Ocean

In terms of impact, AI remains very minor relative to all the other carbon intensive stuff we do. It's a few percent of overall power usage. And unlike many of those things, using renewable power for AI use cases is fairly straightforward from a technical point of view and also the cheapest thing to do long term. A lot of the current rise in emissions is data centers opting for more expensive dirty power because that's all they can get. That's the problem to fix. Because we're going to need a lot of clean power generation to transition away from all the current dirty power generation.

The good news is that that usage is creating high cost for them and an incentive to do something about that. Which is why MS, Amazon, etc. are very interested in investing in e.g. nuclear and renewables.

I'm not too worried about the long term impact of increased power usage by data centers. I think it's more interesting to focus on the big emitters: domestic and industrial heating, shipping, road transport, aviation, construction, etc. There is some movement there but it's very slow. Fixing that should increase demands on power grids and that's a good thing because investments are needed to make that better and cleaner and the most viable technical path to doing that is via renewables.

And it's not a zero sum game. AI delivers economical benefits as well. Including potential savings in labor, efficiency gains, and indeed power usage. I don't think becoming Luddites is really a realistic path. Not going to happen and quite pointless and ineffective to be calling for that. AI is happening and there's going to be more of it. Wasting energy on trying to put that cat back in the bag it escaped from is a mission impossible.
