Ice Capades
Fieldwork is exciting and inspiring, leading scientists to new ideas, places and observations about how the world works.

Spring Courses in Conservation, Ecology & Policy
The Earth Institute Center for Environmental Sustainability (EICES) at Columbia University provides executive training in environmental sustainability through courses in science, economics and policy. We invite you to join our leading experts and practitioners, strengthen your understanding of human-ecosystem interactions, and become an effective environmental leader and decision-maker.
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
