Colombia, a significant exporter of coal/oil, has chosen to stop licensing new exploration & boost other industries, incl. renewable energy, tourism, agriculture - inviting others "to be on the right side of history”. A report by “some very rock star academics” will show how countries can transition

Colombia convenes climate ‘coalition of the willing’ to break global fossil fuel deadlock

Our PhD student Kennedy Orwa, who studies applications of AI to health care, was hastily deported today to Kenya along with his 13-year-old son without opportunity to speak to legal counsel. King 5 reports that he held a valid visa that was rescinded without explanation.

This fetid landmark, this historical stain on humanity is primarily due to the stunningly reckless obliteration of America's foreign assistance agency earlier this year. Led by the richest man on earth. In secret, on a weekend. With zero analysis or discussion of its catastrophic impacts.

I was shocked when I first saw these results from standard climate models used in IPCC reports: for high emissions, the Atlantic overturning circulation #AMOC shuts down in all 9 models that ran past 2100, and is well on the way to shutdown by 2100. Our paper on that is out today.🧵

One of the main benefits of doing a US PhD is the extra time you get, that's one of the big reasons I advised my students to apply for US programmes. We offer a four year degree here, there'd be no advantage over us. The US is euthanising its massive advantage in research for no good reason.

I know there's a lot happening today, but this is sneaking in under the radar. This proposed new rule would absolutely crush foreign PhD students, potentially making it impossible for them to enroll with any certainty of their ability to finish www.politico.com/news/2025/08...

The employment rate of non-EU born migrants exceeded that of the UK-born for the first time on record. Confirms other evidence that recent migrants (even if they did not arrive on work visas) are very likely to be working/have high employment rates.

The White House is taking new steps to undermine every international student at our universities. It has approved a new rule restricting student visas to 4 years max. That's not long enough for PhD students, or about half of undergrads, to finish their degree. Likely to enter force within days.

Trailblazer and economist extraordinaire Mica Sviatschi just got tenure at Princeton! Mica didn’t need much guidance and I bet Miguel Urquiola wisely undid much of my rookie attempts at it, but I’m very proud of the first PhD student I properly co-advised (and the other awesome PhD advisees since)

i just made the mistake of reading the comments on a NYT article on foreign aid. My god, some people are just way too dumb to understand how lucky they are to have been born in a rich country. Not better or more deserving, just lucky. It's so simple and obvious.

I ran @USAID health programs for the last 3 years. Trump’s 90 day Stop Work Order on foreign assistance does serious damage to the world and the US. Examples:🧵
