Earth Institute Science in Spotlight
Research presented by Earth Institute scientists at the 2011 American Geophysical Union fall conference generated a lot of attention from the media. Much of it came from a press conference held to discuss findings by Steve Goldstein from the Lamont-Doherty Earth Observatory and his colleagues on the potential for future drying up of the Dead…

Deploying Instruments on the Seafloor in the Deep Ocean
Oceanic plates are born at mid-ocean ridges, where hot mantle rocks are brought very close to the surface, partially melt, and then cool and crystallize. The newly formed rocks move outwards from the mid-ocean ridge, making way for the next batch of hot rock rising from below. Inch by inch, over millions of years, oceanic…

Nature & Naturalists, an Ode to Adirondack Color
There was a nice article in the NY Times on the Adirondack State Park whose title initially focused readers on how climate change could alter the park’s ecosystems. However, by the time you get to the end of the article, and luckily for us, you get to know Jerry Jenkins, one of the best naturalists…

From Distant Past, Lessons on Ocean Acidification
Oceans turned more acidic during a period of great warming some 56 million years ago, causing an extinction of bottom-dwelling marine species known as foraminifera, a scenario that may be happening again now, only much more quickly.

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.

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…

Seismometer Puts Earthquakes Online at Kent School
A well-traveled seismometer sits tucked inside a concrete chamber behind the Kent School chapel in Northwest Connecticut, recording earthquakes. It got here by chance.
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
