Scientists have long known that large volcanic explosions can affect the weather by spewing particles that block solar energy and cool the air. Some suspect that extended “volcanic winters” from gigantic blowups helped kill off dinosaurs and Neanderthals...

Each year, dozens of small, mostly harmless earthquakes quakes rattle the northeastern United States and southern Canada, and one quite active area runs along the shores of lakes Erie and Ontario, in western New York. In order to learn more about what generates these, and the possible threat of something bigger, scientists at Columbia University’s Lamont-Doherty Earth Observatory have installed a new seismometer at the West Valley Central School, southeast of Buffalo.

On a crisp autumn Saturday, Oct. 2, Lamont-Doherty Earth Observatory opened its doors to the community for its annual Open House: a day of free lectures, demonstrations and workshops for adults and children.

We are proud to announce that in the new rankings of 140 Earth Science Ph.D. programs by the National Research Council (NRC), our program is ranked at the very top!

BP’s leaking oil well in the Gulf of Mexico was conclusively sealed this week, but even now questions remain about the amount of oil that actually came out of it. Now, in the first independent, peer-reviewed paper on the leak’s volume, scientists have affirmed heightened estimates of what is now acknowledged as the largest marine oil accident ever.

As the last ice age was ending, about 13,000 years ago, a final blast of cold hit Europe, and for a thousand years or more, it felt like the ice age had returned. But oddly, despite bitter cold winters in the north, Antarctica was heating up. For the two decades since ice core records revealed that Europe was cooling at the same time Antarctica was warming over this thousand-year period, scientists have looked for an explanation.

Expanded irrigation has made it possible to feed the world’s growing billions—and it may also temporarily be counteracting the effects of climate change in some regions, say scientists in a new study. But some major groundwater aquifers, a source of irrigation water, are projected to dry up in coming decades from continuing overuse, and when they do, people may face the double whammy of food shortages and higher temperatures.

Scientists are in the early stages of building a fiber optic network on the seafloor for observing, in real time, deep-sea hydrothermal vents---places where super-heated water and minerals spew from Earth's crust offering clues about how life on the planet may have began.

The memory of last winter’s blizzards may be fading in this summer’s searing heat, but scientists studying them have detected a perfect storm of converging weather patterns that had little relation to climate change. The extraordinarily cold, snowy weather that hit parts of the U.S. East Coast ...

John Diebold, a marine scientist who sailed the world’s oceans for more than four decades using sound waves to study earthquake faults, underwater volcanoes and other normally hidden features of the seabed, died on July 1 at his home in Nyack, N.Y. The apparent cause was a heart attack, his family said; he was 66.

Scientists still puzzle over how Earth emerged from its last ice age, an event that ushered in a warmer climate and the birth of human civilization. In the geological blink of an eye, ice sheets in the northern hemisphere began to collapse and warming spread quickly to the south. Most scientists say that the trigger...

An earthquake with the following parameters has occurred:
Time: Wednesday, June 23, 2010 at 17:41:42 UTC, 13:41:42 EDT (1:42 PM in NY)
Location: 45.862 °N, 75.457 °W (Southern Ontario), approximately 53 KM (33 mi) NNE from Ottawa
Depth: 18 km (11.2 mi) set by location program

Satellite tracking has shown that the Pine Island Glacier, one of Antarctica's largest ice streams, is accelerating and thus contributing a growing share of the melt water raising sea levels worldwide. A team of scientists visiting the region last year discovered one reason for the speed-up...

In nature, random signals often fall mysteriously in step. Fireflies flashing sporadically in early evening soon flash together, and the same harmonic behavior can be seen in chirping crickets, firing neurons, swinging clock pendulums and now, it turns out, rupturing earthquake faults.

With so many questions still unanswered about the oil spill in the Gulf of Mexico, Lamont Doherty scientists have been providing perspective to the public and press on many aspects, from the spill’s magnitude and spread, to the technologies available to abate it, and its long-term policy implications.
