New capacity being electric is fine but we need to be actively removing fossil fuels from existing capacity, which isn't actually happening. We're just building new capacity on top of old existing fossil fuels. So sure, it's nice that a majority of new capacity is green, but we're still burning more fossil fuels year over year
I’ve had the same discussion with many people, and when I tell them how much work is done on cleaning up carbon emissions, the reply is always “well… it’s not enough”. And of course, they don’t have a sense of what is “enough”.
They don’t really understand it in a factual, measurable way, but just are interesting in what the overall story is, and what it says about humanity failing.
We've been seeing our own certain destruction from climate change coming since the 70s. The 1870s. We had two entire lifetimes to do something about it, we didn't.
Except those guys throwing soup at the fossil fuel HQs. They did a little.
We're building more data centers for a technology that's ramping global warming even faster. Water consumption, heat generation and tons and tons of CO2 emitting concrete to house these things.
So we're doing something, but those things are counterproductive to our planet's general well being. Apparently billionaires don't need an inhabitable Earth to live on.
Growth trend matters more than absolute present value.
Data centres generally had been seeing energy use growing at 12% annually, or with a doubling time of 5.8 years (about 5 years 10 months). AI is accelerating that trend.
In the United States, power consumption by data centres is on course to account for almost half of the growth in electricity demand between now and 2030. Driven by AI use, the US economy is set to consume more electricity in 2030 for processing data than for manufacturing all energy-intensive goods combined, including aluminium, steel, cement and chemicals. In advanced economies more broadly, data centres are projected to drive more than 20% of the growth in electricity demand between now and 2030, putting the power sector in those economies back on a growth footing after years of stagnating or declining demand in many of them.

It would be great for you to experience living close to one of these data centers [0]. Maybe you'd have a consideration outside of your own myopic view then.
It feels like you're being sarcastic but "AI data centers are what, half a percent of the world electricity consumption" -- 0.5% of the global total is huge!
If you think that every data center is now a closed loop system enjoy your propaganda.
Colossus 1 and 2 still use open loop systems. And with the case of blow down water that's "returned" it's not usable due to the use of concentrated salts (1,200 to 6,000 mg/L).
In your mind this is a closed loop system of clean water. It is not. And as DCs have less and less discharge there is more and more solid waste produced.
Your assertion that "water consumption is a red herring" is utter bull shit. I'd suggest enlightening yourself [0][1][2][3].

What do you mean we are doing very little?
It should be at the level od the economy of war but worldwide. The majority reacted too late to have the possibility to act slowly.

Are we measurably slowing down the warming effect?
Both can be true: we are doing a lot, and it's not enough.

Yeah, data-centers are definitely the worst thing happening to the planet. You got your priorities straight.
AI data centers are what, half a percent of the world electricity consumption, if that, and an even smaller fraction of the total energy?

DC water consumption is a red herring. That water is returned back to its source but warmer.
If you think that every data center is now a closed loop system enjoy your propaganda.
