In a UN speech today, President Trump said that "all of these [climate] predictions were wrong". Back in 2019 I led a research effort to digitize old climate model projections and assess how well they did. Turns out they got future warming pretty spot on!

Incentives work!

I'm sorry, what two-bit banana-republic is this video from? Who looks at this and says, "Yep, Land of the Free, Home of the Brave"?

Well, this fills me with confidence in their algorithms! I'm no AI researcher, but "James P. Hughes" doesn't even seem very close to "James H. Jones".

So much for international post-docs at American universities. I guess US Science will slip even further behind. www.nytimes.com/2025/09/19/u...

In case this hasn't made it into your feeds, @lesja.bsky.social @karenguzzo.bsky.social @shelleydclark.bsky.social @drjenndowd.bsky.social Going straight into my lecture slides for this quarter!

One of these rich dudes invested in a food company with all proceeds going to kids in need. The other started Sundance Institute, boosting the lives of countless artists. Hey modern rich dudes, don't be a typical greedy AI crypto-prick, be like these two.

American soybean farmers don’t have a single order from China as they head into harvest season. China usually buys 25% of the entire crop. Crisis looms for the farmers and there’s only one man responsible.

We are at the point in the honoring-Charlie-Kirk's-memory cycle when faculty are being fired for posting, without comment, Charlie Kirk's words. At the behest of politicians sworn to uphold the first amendment, and in public institutions covered by first amendment protections.

people pretend that debate signals and defends a commitment to high minded politics. what it elevates instead is performative dishonesty as a basic mode of politics www.washingtonpost.com/opinions/202...

This is important, but, of course, it won’t get the same kind of attention.

This is predictable, if depressing. @vmminin.bsky.social @dmparker.bsky.social , I guess it's just as well that we didn't get funded because we surely would've had that money pulled!

And yet Trump 2.0 is sprinting away from the one undeniable policy win of Trump 1.0...

“They’re taking our jobs” was always a lie. Alabama proved it. Alabama tried a “tough” immigration law, and it backfired hard. Immigrants fled, crops rotted, and farms collapsed. Americans tried to step in but couldn’t last a day. They’re not taking your jobs; they’re doing the jobs you won’t do.

Leg braces - $20-$30k, I’ve had at LEAST 6 leg braces. Wheelchairs - $5k for manual with no bells and whistles, I’ve had 2 Medications - anywhere between $100-$2000 /month pending health issues Surgeries - 19 surgeries $40k to - $1m inc. hospital stays I had polio. This is the cost.

It used to be the case that Presidents appointed Cabinet Secretaries who were reasonably knowledgable and supportive of the mission of their agencies.

My department is hiring an assistant professor of environmental behavioral sciences. The research area is open but we are particularly interested in people with research on collective action or computational social sciences. Happy to answer questions about the Doerr School or the department.

Call me old-fashioned, but this doesn’t strike me as particularly “presidential”

Concern over low birth rates was what the theocracy in Margaret Atwood’s Handmaid’s Tale used to come to power.

When nation-states stop publishing statistical tables.

An element of fascism is a kind of upside down where the meanest, most rapacious, and least virtuous of society are loosed to bully and abuse people who genuinely uphold civic ideals of service and sacrifice. Public service isn’t what the system is about. It’s about conditioning the national body.

This is a great take (i.e., gamification of politics) on the idea of debate, one that is weaponized to undermine the autonomy and power of colleges and universities.

Pulitzer-calibre photo here. Simply heartbreaking.

We should all strive to be more like Victor.

Silicon Valley power players want a Congress that's pro-AI. They're spending $100 million to try to get it. Our story today on Leading the Future, the new AI-focused Super PAC modeled on the success of the cryptocurrency lobby: www.washingtonpost.com/technology/2... w/ @nitasha.bsky.social

Democracy in action!

Is it just me or is the sycophancy accelerating?

🚨🧵My latest: As measles took off in Texas, the Trump administration took actions that prevented CDC scientists from responding. The outbreak became the biggest in 30 yrs. It’s far larger considering the outbreaks it sparked in other states & Mexico. kffhealthnews.org/news/article...

The government of the Trump administration is not performing its duty to protect and serve the citizens of the United States. This is a chilling example from the recent measles outbreak in West Texas. kffhealthnews.org/news/article...

The kids might still save us.

During this Oval presser, Trump again concealing his right hand but he slipped-up at this moment

A couple observations from all the video from the Oval Office: (1) Trump seems to give all his addresses from behind the Resolute Desk this time around (2) He nearly always has his left hand covering his right hand (3) Super low-energy. This is not the fiery, sometimes funny, Trump of 2017

Medicaid work requirements are back — and mandatory. The last time states tried this, even the ones trying to make it work saw thousands lose coverage. New Hampshire’s experience is a warning. My new article for @donmoyn.bsky.social "Can We Still Govern?" donmoynihan.substack.com/p/what-can-b...

Literally bowing and scraping. I'm pretty sure we've always been anti-king he in America.

Damn, this is good.

I could walk a mile faster than this a couple months after getting a hole drilled through my ankle.

FWIW, "yours for the restoration of the Republic" was a common salutation American fascists gave to each other in the 1950s and 1960s. This is from a 1952 letter by Ohio white supremacist terrorist Peter Xavier. The rest of the rhetoric here might be familiar too.

Gosh, I wonder why they'd have to do that 🤔 www.nytimes.com/2025/08/21/u...

Recently, Microsoft listed 40 careers that would be replaced by AI. Today, a friend sent me a link to a series of ChatGPT prompts where it could not follow a basic request to draw a human with two arms, two legs, and eight spider legs. It kept drawing ten spider legs, despite repeat corrections.

This is quite the all-star lineup of demographers with expertise in fertility. Period fertility (or mortality) rates are not destiny. If we are really that concerned about future population growth, perhaps we should just make it easier for people to have families? It's in our power

“Microsoft also warns against using the AI function for numerical calculations or in ‘high-stakes scenarios’ with legal, regulatory, and compliance implications, as COPILOT ‘can give incorrect responses.’” 🤷🏿‍♂️

This is an amazing article about the train wreck that is the University of Chicago. Very clear implications for R1 universities more generally. www.compactmag.com/article/the-...

Привет, товарищи! It’s another glorious day in which Trump’s America is increasingly indistinguishable from Stalinist Russia, so I thought an armchair comparative analysis was in order. Specifically about Jay Bhattacharya's twin from times past, Trofim Lysenko. open.substack.com/pub/rasmusse...
