Now all done but the synthesis! Thanks to the ~110 scientists and practitioners, not to mention @agu.org and our local volunteers, for a great three days in Montreal!

New paper @igsoc-pubs.bsky.social led by former BS/MS Ella Stewart finds evidence from NASA ICESat-2 that basal friction is low many km upstream of grounding lines over most of Antarctica! Important implications for how quickly glaciers respond to ice shelf thinning.

When we cut critical Federal funds for science, we all pay the price. The impacts of this loss of scientific innovation will be felt especially acutely in our coastal communities. Check out my latest op-ed, published today in The Philadelphia Inquirer, to learn more! share.inquirer.com/iC6tHv

“…vertical land motion projections based on linear extrapolations introduce systematic median sea-level projection errors of typically up to 7.6 mm yr−1 at sites influenced by seismic or volcanic activity and 5.6 mm yr−1 at the other sites”

I wrote something about creativity in science. Why would one write such a thing? That's the first question the piece addresses. There's general reasons, and then there's my current weird personal quest... deepconvection.substack.com/p/creativity...

Crazy how much ice Viedma Glacier (2nd largest in south America) has lost recently! 🧊😱 On this pic taken yesterday, we can see that the right margin has almost reached the south tributary valley occupied by Laguna del Viedma that used to drain periodically into Lago Viedma 🌊 📷 southadventuretrek

Excited to share our latest work, published today in Eos! The U.S. has led and helped to fund about a third of all global sea level projections ever produced. Now, attacks on science in the U.S. have left the field at a precipice.

Thanks to everyone who has reached out about the fire (www.tampabay.com/news/educati...) that completely destroyed more than half of our college. Thankfully no one was hurt -but it’s total devastation to the main building The outpouring of support from the scientific community has been heartwarming

New paper out in Phil Trans R Soc A. We asked a simple question: are the IPCC’s lowest sea-level rise scenarios actually achievable? Short answer: probably not. 🧵 royalsocietypublishing.org/rsta/article...

Nearing the end of semester two at Georgia Tech, and I am so grateful this team who does awesome science. As our group keeps growing, I will always value the work each of them - one amazing postdoc (@yangx309.bsky.social) and the spectacular GATO “undergrad army” - did to help get us off the ground.

We have a new pre-print out, led by postdoc Brian Kyanjo, describing an open-source, interoperable, scalable data assimilation library for ice sheet models including some promising results with two community ice sheet models. Check it out! doi.org/10.48550/arX...

John Christian, former postdoc, now prof at @uoregon.bsky.social, led this study on how ice sheets and sediment work together to make grounding zone wedges, explaining pauses in Antarctic retreat over otherwise smooth reverse-sloping beds during the last deglaciation dx.doi.org/10.1029/2025...

This is an interesting, if provocative perspective. I agree with most of what the authors say except I view the paradigm they advocate as more of a “yes and” rather than a replacement for our current understanding. 1/

3/ We analyzed 18 major Antarctic ice drainage basins using the ice-sheet model #PISM, gradually increasing global mean temperature to map their long-term response. Result: different regions respond very differently to warming.

In general, I think scientists should spend more (any?) time thinking about **why** they do their science, as it would cause them to think more critically about the means **by which** they do it.

His premise is that if astronomy is more and more data science (it is) and if current AI are getting to human-equivalent level at data science (maybe, depends on who you ask), we gotta first discuss WHY people study the stars to then have a good conversation about what to do.

New postdoc opportunities in my group at Rutgers-New Brunswick, working on sea-level rise projections and/or coastal climate risk assessment & management

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

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.
