Stability Check on Antarctica Reveals High Risk for Long-Term Sea Level Rise
The warmer it gets, the faster Antarctica will lose ice, and at some point the losses will become irreversible. That is what researchers say in a new cover story in the leading journal Nature, in which they calculate how much warming the Antarctic Ice Sheet can survive.

Pod of the Planet Ep. 10: The Ice Sheet Goeth
In this episode, Kevin Krajick explores Marco Tedesco’s obsession with the cryosphere—the part of earth that consists of frozen water.

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
