Bordeaux, France, has now recorded more days above 40°C in 2026 alone than during the entire 105-year period from 1920 (when observations began) to 2025. This is deeply shocking.

The US Administration just restricted the duration of student visas. What's the problem? Now political appointees have full discretion to block most international students from staying after graduation. They've promised to use their new power to do just that. My new @piie.com post explains—>

A new US rule to restrict student visas will hurt the US economyThe Trump administration issued a final rule in July that gives it discretion to cut short the course of study of most international students at US universities. It will likely use this new power to b...www.piie.com

Here's a larger data set. Note that the rank order is pretty good! The correlation coefficient is +0.934, where +1.0 is perfect. And a measure of getting the order right, which is called "rank correlation", is an amazing +0.980. tl;dr we're good at comparing, but we are the pits at quantifying

Outstanding insight into likely effects of student visa time limits on study and post-study training. Other countries will absorb some, but not all of the talent. The setback to scientific progress will concentrate in the US but will be global in scope and have lasting if not permanent effects.

Ah but you see he cleverly said “i am not a nazi” which has settled the matter

In May I reported that the Justice Department had filed dozens of lawsuits against immigrants across the country, part of an effort to collect unprecedented fines levied for civil immigration violations. At the time, it had assessed $36 billion in fines. Now that figure is $84 billion, DHS says.

In a conclusion aimed at pleasing Stephen Miller rather than Donald Trump, a White House report criticizes the immigration of scientists, arguing it’s bad whether international students earning PhD’s stay or leave after graduating. @mclem.org @douglasrivlin.bsky.social www.forbes.com/sites/stuart...

You might get sick of hearing this but if he keeps doing it I'm gonna keep saying it: this is an unconstitutional impoundment, violating both Congress' Article I spending authority and the 1974 Impoundment Control act, and immediately impeachable.

2/ Section 338 authorizes tariffs up to 50% on countries that "discriminate" against US commerce. It has essentially never been used. The last recorded activity was a 1935 finding against Germany that went nowhere.
