Damage Uncovered on Antarctic Glaciers Reveals Worrying Signs for Sea Level Rise
A new study has revealed extensive new damage to two major Antarctic glaciers that creates the conditions needed for ice shelf collapse.

Greenland on Track to Lose Ice Faster Than in Any Century Over the Last 12,000 Years
If human societies don’t sharply curb emissions of greenhouse gases, Greenland’s rate of ice loss this century is likely to greatly outpace that of any century since shortly after the end of the last ice age, a new study concludes.

Project Will Delve Into How Climate and Tectonics Shaped Human Ancestors Over 25 Million Years
A new project will investigate the relationships between tectonics, climate and the evolution of humans’ primate ancestors in Kenya’s Turkana Basin.

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.

Ancient Volcanoes Once Boosted Ocean Carbon, But Humans Are Now Far Outpacing Them
A new study of the closest ancient analog to modern carbon emissions finds that massive volcanism was the main cause of high carbon at the time. But nature did not come close to matching what humans are doing today.

Deep Channels Linking Antarctic Glacier’s Underside to Ocean Could Hasten Melting
Newly discovered seabed channels beneath the Thwaites Glacier may be pathways for warm ocean water to melt the ice’s undersides and contribute to sea level rise.

Antarctic Ice Shelves Vulnerable to Sudden Meltwater-Driven Fracturing, Says Study
A new study says that many of the ice shelves ringing Antarctica could be vulnerable to quick destruction if rising temperatures drive melt water into the numerous fractures that currently penetrate their surfaces.

Greenland Ice Sheet Saw Record Loss in 2019
An international team of polar researchers says that the Greenland ice sheet experienced record loss in 2019.
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
