Scientists can remotely detect landslides with seismometers. The data contains critical information about the source and size of the rock falls.

A new study co-authored by Lamont-Doherty scientists Paul Olsen and Dennis Kent pins down massive eruptions that may have triggered the mass extinction about 201 million years ago that led to dinosaurs ruling the Earth.

We all know a gigantic asteroid is to blame for wiping out the dinosaurs--but what wiped out the animals that came before them?

Eruptions that ripped apart continents in the Triassic also caused mass extinctions, says a new study co-authored by Lamont-Doherty scientists Paul Olsen and Dennis Kent.

More than 200 million years ago, toothy crocodile-like creatures stalked a hot, dry mega-continent while squid-like mollusks with spiral shells drifted in the surrounding ocean.

"People have been running up and down the river for hundreds of years. Now there's all sorts of stuff down there," said Lamont’s Robin Bell. N.Y.

Coming decades could see delays in summer monsoon rains in the U.S. Southwest and northwestern Mexico that water crops for 20 million people, according to a new study by Lamont-Doherty scientists Benjamin Cook and Richard Seager.

Lamont-Doherty's Klaus Jacob, a professor specializing in climate-change adaption, on the sorts of planning that might help prepare for an era of rising seas.

The science is yet unclear as to whether climate change influenced Hurricane Sandy, says Lamont-Doherty scientist Adam Sobel.

Did humans start altering the climate by farming, long before industrialization? Lamont-Doherty climate scientist Wally Broecker is one of the skeptics.

Big droughts have hit New York City's watershed in the past 500 years. More research from scientists at Lamont-Doherty suggest it could happen again.

Lamont-Doherty seismologists Paul Richards and Won-Young Kim discuss their analysis of North Korea's nuclear test in this video piece.

Sea surface temperatures in the Pacific Ocean have historically helped define climate variation in the American Southwest but as climate warms the region will become drier overall, says Lamont-Doherty scientist Richard Seager.

Lamont-Doherty seismologist Paul Richards quoted in a story about North Korea's nuclear ambitions.

Data from a seismic station in China confirms that North Korea is getting a lot better at building nuclear bombs. The good news: they can't hide their tests from seismologists. Lamont-Doherty seismologists Paul Richards and Won-Young Kim weigh in.

In the wake of Hurricane Sandy, scientists and officials are trying to protect the largest US city from future floods. “Ultimately, we all have to move together to higher ground,” says Lamont-Doherty scientist Klaus Jacob.

Lamont-Doherty scientist says a seawall may only protect Hoboken in the short-term from rising seas.

North Korea's first test is largely believed to have fizzled, with a yield of less than 1 kiloton, and the second was between 2 and 7 kilotons. "The first test almost failed. The second one showed they could basically do it. The third one showed that this is really working," said Lamont-Doherty seismologist Won-Young Kim.

Lamont-Doherty seismologist Paul Richards calls North Korea's nuclear blast on Tuesday "a serious explosion."
