Check out this new paper we have in @pnas.org ! It’s got some big findings about glacial erosion. Namely that quarrying is ~5x more efficient at eroding bedrock than abrasion and that power based erosion laws are the most appropriate for modeling erosion www.pnas.org/doi/10.1073/...

One of the climate modeling preprints that I cited in my feature, finding that AMOC was resilient and reversible to realistic Greenland melt, is out now in Science Advances. Not shockingly, it hasn't gotten broad coverage.

Climate model simulations show the Atlantic overturning circulation can recover even from strong future Greenland ice sheet melt.

Our newest Dr from ICCL, Dr. Danielle Grau! 🎉🧊❄️🐝

Our last Ice-T talk from postdoc Dr. Paul Summers 🥲 where he imparted sage wisdom to students and summarized his very successful two years of work with myself and Becca Jackson at Tufts. He is off to a position @sandialabs.bsky.social!

First talk by @donglaiyang.bsky.social: calibrating remote sensing observations in a probability space using an ensemble composite. Then discovering anomalies in radar attenuation rate & thus ice temperature. Finding (hypothesized) ~10-100m of temperature ice under parts of Thwaites Glacier. #igsoc

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...

Creativity in science: why talk about it?

Because we usually don't, and we aren't good at teaching it either.
