Giant CO2 Eruptions in the Backyard?
Northern New Jersey, southern Connecticut and environs are not necessarily where one would expect to explore the onetime extinction of much life on earth, and subsequent rise of dinosaurs. But it turns out to be a pretty good place to start. Underlying the exurbs are geological formations left by three giant episodes of volcanism starting around 200 million years ago, and…

The Last Arctic Sea Ice Refuge
If climate change proceeds apace, summer sea ice in the Arctic is projected to nearly disappear by the end of this century. But a group of researchers predicts that ice will continue to collect in one small area, perhaps providing a last-ditch stand for ringed seals, polar bears and other creatures that cannot live without…

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
