Humanity already produces enough calories to feed everyone, yet billions go hungry while others over-consume. New EAT-Lancet Report provides the science and the moral imperative to solve this problem, write experts @jessfanzo.bsky.social and Bianca Carducci: news.climate.columbia.edu/2025/10/03/a...

Farmer holding a basket of plants in a field with text: Why now? Today's food system is breaching planetary boundaries and driving global health inequalities. The EAT-Lancet Commission outlines a pathway for transformation grounded in science, justice, and real-world, solutions.

Team led by @seismoshuck.bsky.social with LDEO's Suzanne Carbotte, Anne Bécel, colleagues has directly observed subduction zone actively breaking apart, shedding new light on how Earth’s surface evolves & raising new questions about earthquake risks in Pacific NW: lamont.columbia.edu/news/earths-...

Researchers and crew aboard the R/V Marcus G. Langseth during the 2021 Cascadia Seismic Imaging Experiment (CASIE21) experiment, which collected seismic data to image the Cascadia Subduction Zone analyzed in the new study. About 20 scientists from Lamont-Doherty Earth Observatory, Louisiana State University, University of Washington, and a number of other institutions are analyzing the dataset as part of the Cascadia Region Earthquake Science Center (CRESCENT), a community studying earthquake hazards in the Pacific Northwest. Lamont’s Suzanne Carbotte, seated first row second in from the right, is the chief scientist for CASIE21, which is supported by the National Science Foundation.
