The Climate Epochs That Weren’t
Climate scientists often invoke the Medieval Warm Period and the Little Ice Age as natural worldwide climate swings predating human influences. They may not have worked the way we think.
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
