“AI is famously energy-intensive and requires a ton of water in order to cool the data centers and server farms that act as the program’s brain. Researchers at the University of California Riverside (including Ren) & the University of Texas Arlington recently found that training ChatGPT-3 alone required roughly 185,000 gallons of water—that’s enough water to fill a nuclear reactor’s cooling tower.” #ClimateCrisis

Google Is Really, Really Thirsty

Google said it consumed 5.6 billion gallons of water in 2022—its push into AI is likely to make that amount skyrocket.

It’s really too early to say how meaningful it is from a climate perspective, since it takes 10-20 years of data to form a recognizable climate trend.

If there is a shift from the 1981-2010 baseline, that’s useful to know but the meaning is unclear because we don’t know what that trend looked like pre-1981 with such high resolution.

If Antarctic ice doesn’t recover year after year after year, and then the same trend happens in the Arctic as well…then that would be significant.

This chart is making the rounds and freaking out a lot of people, but what does it really show?

There’s definitely a detectable departure from recent historical averages this year. Here’s what the UC Boulder National Snow and Ice Data Center has to say about sea ice extent this year: https://nsidc.org/arcticseaicenews/

The question is: How well does the Antarctic ice recover when it peaks later this year? And what is the multi-year trend, especially as this year’s super El Niño fades?

“I think we should be very worried,” said Prof Peter Ditlevsen, at the University of Copenhagen in Denmark, and who led the new study. “This would be a very, very large change. The Amoc has not been shut off for 12,000 years.” #ClimateCrisis

Gulf Stream could collapse as early as 2025, study suggests

A collapse would bring catastrophic climate impacts but scientists disagree over the new analysis

Today Fervo Energy announced breakthrough well test results at their full-scale commercial pilot, Project Red, confirming the viability of Fervo’s next-generation #geothermal technology. This establishes Project Red as a productive enhanced geothermal system.

As Jesse Jenkins of Princeton University noted, “Fervo’s successful commercial pilot takes next-generation geothermal technology from the realm of models into the real world.” https://fervoenergy.com/fervo-energy-announces-technology-breakthrough-in-next-generation-geothermal/
