Photo Essay: Melting Greenland, Up Close
As climate warms, the Greenland ice sheet is melting, helping to fuel global sea-level rise. Follow a small team of scientists as they hike onto the sheet to investigate the forces large and small that are demolishing the ice.

Short-Term Ocean Temperature Shifts Are Affecting West Antarctic Ice, Says Study
Scientists have known for some time that ice shelves off West Antarctica are melting as deep, warm ocean waters eat at their undersides, but a new study shows that temperatures, and resultant melting, can vary far more than previously thought, within a time scale of a few years.

An Icy Irony in Greenland
We awoke to messages that a towering iceberg is threatening the local waterfront settlement of Innaarsuit. There is perhaps a bit of irony in the fact that a massive looming block of ice is a potential threat to the start of our field season.

Exploring Greenland With Wings, Boats and Drones
Snow on Ice is launching into the field with two teams of scientists this summer. The first group, an ‘advance team’ of six women, will focus on lakes where meltwater has collected on the southwestern flank of Greenland bedrock.

Study Signals Change in How Scientists Calculate Ancient Diets
Scientists have long determined what extinct animals ate by analyzing carbon isotopes locked inside their fossil teeth. But a new study shows that in many cases, they may be plugging the wrong numbers into their equations. The findings may change some views of how mammals, including us, evolved.

James Hansen’s Climate Warning, 30 Years Later
Three decades after Hansen first warned Congress about global warming, the overwhelming scientific consensus is that he was right—and most would say that far too little has been done to address the threat.

How Will People Move as Climate Changes?
A new model estimates how many climate migrants there will be, where they are likely to go, and what effects they might have on the places to which they move.
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
