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 Sea.
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.
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.
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.
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 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 forecasts of the effects of climate change on food supplies.
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 University’s Lamont-Doherty Earth Observatory. Peteet presented new results from her Hudson River work Monday at a press conference at the AGU’s fall meeting in San Francisco.
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 [...]
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 its own tasty dishes to the feast, mostly under the hydrology section of the menu.
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 [...]
