    Switchyard Project: Tracking the Arctic Seascape

    Arctic summer sea ice is declining rapidly: a trend with enormous implications for global weather and climate. The multi-year Arctic Switchyard project will seek to distinguish the effects of natural climate variability from those of human-induced climate change.

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
