Defying Some Expectations, Southern Ocean Did Not Increase Carbon Uptake in Ice Ages
In much of the world ocean, there is evidence that iron-rich dust blowing from land has fertilized algae during cold period, increasing uptake of carbon from the air, and keeping things frigid. Not here, says a new study.

Solar Energy Explains Fast Yearly Retreat of Southern Ocean Sea Ice
Sea ice in the Southern Ocean retreats each year much faster than it develops. This has puzzled scientists, but the explanation turns out to be simple.

Sea Ice That Slowed the Flow of Antarctic Glaciers Abruptly Shatters In Three Days
Since 2011, a mass of sea ice from the Larsen B ice shelf helped stabilize the landward glaciers, but the stopgap rapidly disintegrated in January 2022.

Crucial Antarctic Glacier Likely to Collapse Much Earlier than Expected
Thwaites Glacier, dubbed Antarctica’s ‘doomsday glacier,’ has been predicted to undergo dramatic changes, with its ice shelf likely to break apart in as little as five years.

Study of West Antarctica’s Deep Past Reinforces Vulnerability to Melting
The continent’s western ice sheet turns out to once have been much bigger than previously thought. This implies that the now smaller version could waste quickly.

Scientists Track the Sudden Disappearance of an Antarctic Ice-Shelf Lake
A rarely seen phenomenon may not bode well for the future survival of the ice.
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
