The Greenland Ice Sheet Is Sponging Up Meltwater
As climate warms, the surface of the Greenland ice sheet is melting, and all that meltwater ends up in seasonal rivers that flow to the sea. At least that is what scientists have assumed until now. A new study has shown that some of the meltwater is actually being soaked into porous subsurface ice and…

NASA Finds New Way to Track Ozone By Satellite
Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. But it not directly measurable from space, due to the abundance of ozone higher in the atmosphere, which masks the surface. Now, researchers have devised a way to use satellite measurements of the precursor gases that contribute to ozone formation to…

Giant Boulders on Bahamas Coast Are Evidence of Ancient Storms and Sea Level, Says Study
A new study says that storms of intensities seen today, combined with a few meters increase in sea level, were enough to transport coastal boulders weighing hundreds of tons more than 100,000 year ago.

Expedition Explores Undersea Rift off Greece
The Corinth rift is one of the most seismically active areas in Europe. Starting this month, researchers will drill into the rift to discover its past and future.
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
