As James says, this isn't even about climate.
It's about all the tools, platforms, models, datasets we use to study and forecast weather and understand how it impacts people, too.

These people are nuts. NCAR developed the GPS dropsonde, which revolutionized the understanding of TC structure, improved forecasts, and validated remote sensing platforms, as documented in over 400 peer-reviewed publications in the last 25 years. And that’s just one of NCAR’s countless advances.
Exclusive: The Trump administration is moving to dismantle the National Center for Atmospheric Research in Colorado, according to a senior White House official, taking aim at one of the world's leading climate research labs.

Dismantling NCAR @ncar-ucar.bsky.social is a bad decision for many reasons. NSF’s investment in NCAR scientists, technical staff, facilities and research products supports and catalyzes atmosphere, ocean, and Earth system science across the nation and world with a substantial ROI.

Her sister wrote my favorite essay about her. She points out that RF would have been famous even if she'd never looked at DNA

Remembering my sister Rosalind Franklin
Rosalind Franklin died of ovarian cancer in 1958 aged 37 years. Sympathy and feminism
have combined to give us her familiar image as a downtrodden woman scientist, brilliant
but neglected, a heroine t...

The question about additionality stands, but more importantly, what about the foundational assumptions: 1) All of the carbon in oyster biomass is sequestered from the atmosphere for decades (false - it is respired), and 2) All of the sedimented organic carbon is permanently buried (evidence?).

I was in the process of hiring a postdoc, so this severely affects her career because now she has to look for something else. It also means I can't pay my existing people, can't buy supplies for the lab, and can't travel. Every NSF-funded researcher will be in the same boat soon.

The Act prohibits actions that “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect” endangered species. Right now, “harm” includes damage to a species’ habitat—but the Trump administration is attempting to strip habitat destruction from that definition.

Thanks for the heads-up, Clark. A keen student could learn a lot by modelling the interactions between ambient irradiance spectra and LDR sensor spectral response in different water types through the open ocean. Could be a good publication!
