This fellowship was a huge part of the reason I am continuing to do climate science, and it has supported so many incredible people. These effects on early-career researchers, who do some of the most impactful work, is going to have long-lasting implications for science and scientists.

The Secretary of Commerce's new policy requiring his personal review of all NOAA contracts over $100,000 is directly harming American science. 🧪

How do I know? Because this morning, twelve of America's rising leaders in climate science (including myself) were furloughed.

The bottom line with the proposed cuts to NSF is to cut the number of working scientists and disappear opportunities to train new scientists.

This is a PROPOSED budget to Congress. Call your reps.

I wrote about Trump cuts at the ends of the Earth, to NSF support of science in Antarctica. 🧪

“We’re all trying to find other ways of doing our research,” says @leighstearns.bsky.social, “because they are not the stable entity.”

Does US science have a future in Antarctica? Trump cuts threaten to cancel fieldwork and more

Funding for the National Science Foundation, which finances research at US bases on the icy continent, has already been reduced, and the agency faces steeper cuts soon.
