Our latest piece, just out
The food chains on modern Caribbean coral reefs may have shortened by up to 70% compared with those on their prehistoric counterparts, according to research in Nature. The findings suggest that modern reefs could be increasingly vulnerable to external stressors and ecosystem collapse. 🌍 🧪
Fossil isotope evidence for trophic simplification on modern Caribbean reefs - Nature
Using nitrogen isotopes from ancient and modern fish otoliths and corals, the study shows Caribbean reef food webs are now 60–70% shorter and functionally less diverse, indicating human-driven trophic simplification and increased risk of collapse.

I really do hate that people who are geological illiterate keep pointing to records compiled by paleoclimatologists to downplay climate change because, if anything, the lessons of deep time only emphasize how extraordinary and unprecedented the rate of modern warming is.

Great piece out today in Physics Today on historical origins, contemporary relevance, & fundamental irreplaceability of the National Center for Atmospheric Research, which remains at imminent risk of dismantling for partisan political reasons.
What the National Center for Atmospheric Research means to the atmospheric sciences
Born out of a time of great need for the federal government, NCAR plays a role with few analogues.

And “protest,” in a narrow sense, isn’t even the right term for what we are seeing now. Crucially, in reaction to the regime sending an occupation force of masked goons, a new form of resistance emerged: Communities organizing to help their neighbors, confrontational but peaceful.

🚨 The Senate has agreed to a deal to vote on 5/6 full appropriations bills and replace the DHS funding measure with a 2-week stopgap bill, per multiple sources. That gives time to negotiate on the Dem demands for ICE and CBP restraints.
