Carbon Lurking in Deep Ocean Threw Ancient Climate Switch, Say Researchers
A million years ago, a longtime pattern of alternating glaciations and warm periods dramatically changed, when ice ages suddenly became longer and more intense. Scientists have long suspected that this was connected to the slowdown of a key Atlantic Ocean current system that today once again is slowing. A new study of sediments from the…

Changes in Ocean ‘Conveyor Belt’ Foretold Abrupt Climate Changes by Four Centuries
Led by Lamont-Doherty researchers, a new study is the first to measure the time lags between changing ocean currents and major climate shifts.
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
