AGU Honors Scientists from Lamont-Doherty
A half-dozen Lamont-Doherty Earth Observatory scientists were to be honored by the American Geophysical Union at its annual fall conference in San Francisco tonight.

Where Continents Divide, and Rocks Rise from the Deep
Along the Woodlark Rift in eastern Papua New Guinea, continents are breaking apart, “like a snake opening its mouth.” Geologic processes that are still a mystery are actively stretching the crust and pushing huge masses of rock, formed under immense pressures as deep as 100 kilometers below, to the surface.

Natural Disasters: The Upside
Floods, volcanoes, earthquakes–really, very little good news comes out of this sort of thing. Maybe the occasional feel-good story about, say, a child miraculously dug from the rubble days later, tired but unharmed and in good spirits, having survived on a cache of crackers and Coke. Actually, says John Mutter, an Earth Institute professor of sustainability studies, disasters can sometimes…

A Meeting of Science and Human Impact
A talk Monday by Cynthia Rosenzweig of the Center for Climate Systems Research serves as a good example of how some of the hard science being discussed at the American Geophysical Union’s fall meeting intersects directly with human welfare. She outlined the progress of a new global project that will help scientists produce more accurate…

Ancient Dry Spells, Future Risk?
The last major drought to hit the northeastern U.S. lasted three years and shrunk New York City’s reservoirs by nearly three quarters. But as bad as that drought was, the region has seen at least three dry spells in the last 6,000 years that were far worse, says Dorothy Peteet, a climate scientist at Columbia…

Under the Dead Sea, Warnings on Climate and Earthquakes
An international team of scientists drilling deep under the bed of the Dead Sea has found evidence that the sea may have dried up during a past warm period analogous to scenarios for climate change in coming decades. With nations in the volatile region already running short on water, the finding could be a…

At AGU, Earth Institute’s Columbia Water Center Adds to the Abundance of Scientific Riches
The annual American Geophysical Union (AGU) meeting is an all-you-can-eat buffet of the most current scientific knowledge available on the planet. Name your pleasure: space, climate change, geomagnetism, nonlinear geophysics, volcanology, biogeosciences, etc. You have to be careful to indulge in moderation over the five-day event, or risk unseemly bloating. The Columbia Water Center contributed…

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
