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…

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.

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…

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…
