Proposed NOAA budget zeros out ALL climate laboratories and cooperative institutions. GFDL, NSSL, GML, etc. This appears to also end the US greenhouse gas sampling network, including at Mauna Loa, the oldest continuous carbon dioxide monitoring site on Earth. www.commerce.gov/sites/defaul...

I'm advising one NSF graduate fellow working on understanding how heavy elements produced by the first stars mixed into subsequent generations of stars, ultimately leading to our own existence, and have another considering thesis work with me on planet formation.

Well... I just found out today that the proposed FY26 president's budget will eliminate the NSF graduate research fellowship program that is funding my Ph.D. I have an award in progress, too. This won't just affect future funding or applications.

Immediately after the Vietnam War, I just opted out of the pledge entirely in sixth grade. My homeroom teacher (also taught classical history) had me provide a written justification, and the rest of the year I stayed seated and silent.

A huge blow was dealt to hurricane forecasters this week as a critical tool was abruptly terminated by the Department of Defense and NOAA. The immediate discontinuation of data from three weather satellites will severely impact hurricane forecasts this season and beyond. More ⬇️

Perplexity suggests: 'The "Colby" referenced here is most likely Elbridge Colby, a former U.S. Deputy Assistant Secretary of Defense and a prominent defense policy analyst. He is known for advocating a significant military buildup, especially regarding U.S. alliances in Asia to counter China.'

Indeed. I'd love to see NYC as civilized as Paris was when I visited last summer. Blooming parks, extensive bicycle network, street dining, single payer healthcare. Now, admittedly, they also have serious issues with affordability of housing, but on the margin, yep, I'd take it.
