I’ve spent more than a year reporting on how the fossil fuel industry has infiltrated academia over the last 30 years, shaping fundamental paradigms on how to address climate change. My first story in the new @propublica.org and @drilledmedia.bsky.social series, “Carbon Captured”, is out today.
NEW: This is the story of how one of the most influential climate papers in history came to exist thanks to one of the companies most responsible for causing the climate crisis — and one with a financial stake in the technologies described in the paper. w/ @drilledmedia.bsky.social
Solar geoengineering is often portrayed as a relatively cheap and easy fix for climate change. But as researchers take a harder look at the nuts and bolts of the concept, they’re finding numerous uncertainties, missing machines, and big things that would still need to be built (like polar airports).
Hacking the atmosphere: Geoengineering gets a reality check
Researchers are starting to explore the tools and systems we need to develop to cool down the planet.

More & more solar geoengineering research is moving beyond computer modeling, delving into the design & engineering work needed to develop aircraft, dispersion systems & more. Much of it is happening at @davidkeith.bsky.social's new group at the University of Chicago: Freebie link for my latest:

Re: Patagonia v. Pattie Gonia I spoke with a trademark attorney and two scholars of Indigenous Patagonian history to understand both the legal and ethical question everyone is asking. The answers are way more complex than social media is making them out to be.
Can Patagonia© own Patagonia?
And more importantly, should it?

Despite the growing hysteria over AI’s threat to white-collar jobs, there’s still scant evidence that the technology has had a large-scale impact on the labor market.
A reality check on the AI jobs hysteria
What do the numbers really say about the impact of artificial intelligence on the labor market? The answer might surprise you.

I'm @ Google I/O in sunny Mountain View today, and I'll be sharing my thoughts here throughout the day. We're just over halfway through the keynote now, and one thing is already pretty obvious—Google isn't coming for Anthropic and OpenAI's shared agentic coding crown anytime soon
I'll be reporting on the Musk v. Altman trial at the Oakland courthouse for @technologyreview.com. I'm a lawyer who clerked for a federal judge in California, so follow me to unpack what's really happening in the courtroom! www.technologyreview.com/2026/04/27/1...
Elon Musk and Sam Altman are going to court over OpenAI’s future
Elon Musk says he’s suing to save the company’s mission. The case could have huge consequences for OpenAI and the AI race.

A scoop: DHS is using AI video generators from Google and Adobe to make content shared with the public. It comes as workers in tech have put pressure on their employers to denounce the agency's activities. www.technologyreview.com/2026/01/29/1...
DHS is using Google and Adobe AI to make videos
Immigration agencies have been flooding social media with bizarre, seemingly AI-generated content. We now know more about what might be making it.

I did a lengthy interview with the CEO of Stardust, in which he walked back the solar geoengineering startup's testing and deployment plans a bit. The company also intends to release details about its proprietary particles early next year and expects to open a US office soon.
How one controversial startup hopes to cool the planet
And why many scientists are freaked out about the first serious for-profit company moving into the solar geoengineering field.

They’ve cost hundreds of billions of dollars so far, and require an incredible amount of energy to operate. @technologyreview.com reporter @caseycrownhart.bsky.social shares the latest news on the boom in data centers to power AI.
As Companies Build Data Centers For AI, Communities Push Back
A boom in construction of AI data centers is facing backlash over soaring electricity and water usage, and the resulting utility hikes.

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.

🚨 If you're interested in working on a coordinated response to the DOE climate report, please enter your info on this google form 🚨 Please RT this so as many people see it as possible. forms.gle/BL9xUAfRxA...
DOE climate report response form
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.

The Data Foundation is fundraising for a new initiative that will coordinate efforts among nonprofits, experts & companies to modernize US greenhouse-gas measurements, striving to build on a Biden effort that Trump nullified on his first day in office.
How nonprofits and academia are stepping up to salvage US climate programs
The Data Foundation, the American Geophysical Union, and a coalition of universities are scrambling to ensure that the nation accurately assesses the growing dangers of global warming.

Sam Altman says an average query to ChatGPT uses about 0.34 watt hours of electricity in a new blog post. But I have some questions about this number (short 🧵) #energysky
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.

Power Hungry
An unprecedented look at the state of AI’s energy and resource usage, where it is now, where it is headed in the years to come, and why we have to get it right.

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.

In 2019 I was the first journalist to embed within OpenAI to profile them. Afterwards they refused to speak to me for 3 years. Here's the story of what happened, and Altman’s reaction, excerpted from my book EMPIRE OF AI about the company (out May 20). 1/ www.technologyreview.com/2025/05/19/1...

Amazing when federal agencies suddenly have no communications staff. Love it when there is no way for the public to learn about the work of their government.
