Our neighbors in Minnesota are standing up for the rest of us. Let's stand up with them.

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

Buoyancy Feedbacks on Wave‐Induced Melting of Icebergs Buoyant convection from wave-induced melting acts to shield icebergs from warm seawater, reducing wave-induced melting Parameterizations that do not include realistic depth-dependent wave velocit...

New year, new paper out in JGR:Oceans! Led by PhD Candidate Madeline Mamer - she updates a 40-year old theory for the rate of iceberg erosion by waves, to include the effect of local ocean stratification by meltwater ❄️🥼🧊🌊 doi.org/10.1029/2025...

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 was a pleasure to be able to share my research this year at #AGU2025 @agu.org @agucryo.bsky.social

Awesome turnout in support of @ncar-ucar.bsky.social at #AGU25. Take a look at how many people use our products!

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.
