Our neighbors in Minnesota are standing up for the rest of us. Let's stand up with them.
I wrote about my childhood friend Alexi Pretti. Please read it and share it and remember him as a human being. @theverge.com

The kind-hearted ICU nurse shot by ICE agents was my childhood best friend.

We knew the NSF letter about NCAR would come. I think this is an occasion that will require great coordination and strategical thinking. UCAR should respond as a block, coordinating a response across universities (especially in the South, and large public universities that use NCAR data a lot)

They refer to the section of the national climate assessment i led as “stomach churning” and I’m proud to have caused physical discomfort
Ugh. Is the Administration illegally undermining climate work in America…?

It was an odd choice to pave this section south to north, as the new-build bridges were all on the southern side. The northern half this segment without bridges likely could have been delivered much earlier.

It is hard to overstate how critical @ncar-ucar.bsky.social is to climate science in the US and around the world. It's the beating heart of our field. Generations of scientists have trained there, and almost everyone I know relies on deep collaborations with NCAR scientists. It's end is unthinkable.
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.
