In an op-ed for TR, @davidkeith.bsky.social & @danvisioni.bsky.social voice deep concerns about Stardust & other for-profits racing into solar geoengineering — and asserting claims that, they argue, the science doesn't support.
Why the for-profit race into solar geoengineering is bad for science and public trust
Two scientists argue that the growing commercial efforts to counter climate change by reflecting away sunlight will thwart responsible research in the field.

We've finally got some hard numbers on AI's energy demand from a major tech company: Google says a median prompt to Gemini uses 0.24 watt-hours of electricity. 🧵 @technologyreview.com www.technologyreview.com/2025/08/21/1...
In a first, Google has released data on how much energy an AI prompt uses
It’s the most transparent estimate yet from one of the big AI companies, and a long-awaited peek behind the curtain for researchers.

We are collecting names to assemble a writing team to respond to the DOE climate working group report. If you'd like to contribute, enter your info below. At this point, there is no guarantee what we'll do (if anything), but we want to keep our options open by collecting names. If you have any further questions, feel free to email me. We are primarily looking for Ph.D. scientists at universities or government labs in appropriate fields. I realize that this will exclude some qualified people and I apologize, but we felt this was necessary for a variety of reasons.

I dug into the NSF cuts & other ways that the Trump administration is shutting down climate science.

“Basically it’s a shit show,” Princeton’s Michael Oppenheimer says, “and how bad a shit show it is will depend a lot on what happens in the courts and Congress over the next few months.”
The Trump administration has shut down more than 100 climate studies
Tens of millions of dollars in NSF grants have been slashed, and scientists fear the US is about to lose a generation of climate researchers.

We’re all talking about AI and energy demand, but there’s still a lot of question marks. So @jamesmodonnell.bsky.social and I got together and did some math.

After six months of reporting, we found that AI's energy demand is anything but constant, and the common understanding is full of holes.
We did the math on AI’s energy footprint. Here’s the story you haven’t heard.
The emissions from individual AI text, image, and video queries seem small—until you add up what the industry isn’t tracking and consider where it’s heading next.
