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
I grew up with Alex Pretti
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)

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.

Grad student Tanner May has a new fun paper out in the Journal of Glaciology that is kind of magical. The magic trick that Tanner performs is that he manages to estimate thickness of glaciers using only surface elevations and nothing else.
This shouldn't work, but it does. Let me tell you why.

Really interesting new paper showing ice "sliding mechanically destroys the ordered crystal lattice of ice, creating an amorphous layer that thickens as the sliding goes on". Maybe this explains some things related to subtemperate sliding?
