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?
