Floridaโ€™s Board of Governors is made up of โ€œpolitical appointees from the business world, from insurance executives to roofing contractors, who are dictating how professors must teach their courses and even providing state-created textbooks for doing so.โ€

Kristi Noem Didnโ€™t Give a Sh*t About โ€˜the Detailsโ€™ Such as a woman who was here legally and helped the homelessโ€”but was then deported anyway.

NEW: Here's the story of a woman deported by Kristi Noem. Legally in the United States (as a DACA recipient), she is the mother of a U.S. citizen and was working to help the homelessโ€”but when she went for an appointment to get a green card, she was deported.

"U.S. military investigators believe it is likely that U.S. forces were responsible for an apparent strike on an Iranian girls' school."

"The strike would rank among the worst cases of civilian casualties in decades of U.S. conflicts in the โ€‹Middle East."

The highly specialized nature of the NCAR-Wyoming Supercomputing Center (NWSC) infrastructure represents an extraordinary value proposition that cannot be replicated by combining it with more generalized NSF programs.

Far more than just an office building, NSF NCAR Mesa Lab is an iconic and purpose-built facility designed specifically for the study of atmospheric science. Its position at the physical interface of the Rocky Mountain foothills and the Great Plains is a deliberate reflection of its mission, serving as a visible symbolโ€”in an iconically American settingโ€”of the federal government's enduring commitment to science in service of society. For many in the field, including myself, the Mesa Lab holds singular importance as a focal gathering point for the global atmospheric science community.

I just submitted my letter to NSF responding to its proposal to dismantle the National Center for Atmospheric Research (NCAR). I argue that doing so would be an astonishing and avoidable misstep, and that federal support for the institution should in fact be *increased.* [1/4]
