Lamont-Doherty geophysicist Klaus Jacob has been warning about how vulnerable New York City is to violent weather for years and, more importantly in his view, how climate change and rising sea levels will transform the shape and character of the metropolis.

In the debate over the environmental risks tied to hydraulic fracturing, the state has overlooked one threat that could give New Yorkers a jolt: the potential for wastewater disposal to trigger earthquakes, writes Lamont-Doherty seismologist Geoff Abers in this op-ed.

Three expeditions are now underway to drill deep beneath the surface of Antarctica, where sub-glacial lakes may hold clues to what life could be like on other planets. The Antarctic lakes are thought to hold "whole ecosystems that have never really been looked at," said Robin Bell, a research scientist at Lamont-Doherty.

Robin Bell, a senior research scientist at Lamont-Doherty, who studies the behavior of ice sheets with radar and other techniques, said the subglacial Antarctic lakes hold “whole ecosystems that have never really been looked at.”

A team of geophysicists including Lamont's Gisela Winckler has published a study that suggests the relatively rapid warming of earth's poles may be down to a lack of cooling surface dust, which kept land frozen during the last ice age.

Many Himalayan glaciers are melting and will continue to melt even if global temperatures stabilize, according to a new study by Lamont's Joerg Schaefer and colleagues.

Today's Please Explain is all about helium and the helium shortage. We speak with Dr. Martin Stute, a noble gas geochemist at Barnard college and Lamont-Doherty and with Dr. Joe Peterson a Bureau of Land Management Assistant Field Manager for Helium Resources in the BLM Amarillo, Texas Field Office.

Colorado River flows are likely to shrink by 10 percent in coming decades as the climate warms, according to a recent study led by Lamont's Richard Seager in the journal Nature Climate Change.

Maps detailing actual and expected flooding show that Sandy's storm surge exceeded many of the 100-year flood zones, seeping into places previously considered safe. In a study that's under review at a scientific journal, Lamont scientist Adam Sobel estimates that Sandy’s trajectory was a one-in-a-700-year-event.

For the past decade and a half, governments around the world have been investing in elaborate plans to climate proof their cities. Lamont-Doherty scientist Klaus Jacob weighs in on options for New York.

Lamont-Doherty scientist Klaus Jacob makes Time magazine's 2012 list, People Who Mattered, for his prediction about New York City's vulnerability to a storm surge.

The more greenhouse gases push up temperatures over the next few decades, the more New Mexico’s water supplies are at risk, according to new research led by Lamont-Doherty scientist Richard Seager.

A climate change study by scientists at Lamont-Doherty is projecting declines in runoff in many parts of the West, a scenario that would put more pressure on the region's water supplies.

Lamont-Doherty scientist Andy Juhl has found that debris washed up after Hurricane Sandy showed signs of sewage contamination.

A new study by a team of researchers at Lamont-Doherty predicts a 10 percent drop in the Colorado River's flow in the next few decades which could disrupt longtime water-sharing agreements between farms and cities in the U.S. Southwest.

New York City is poised to finish its warmest year since modern record-keeping began, with an average temperature projected to top 57.2 degrees. As a symbol, Sandy was significant, said Lamont-Doherty scientist Adam Sobel. "But if next year doesn't break the record again, it won't mean global warming has slowed," he said.

The state of Ohio shut down a disposal well for waste fracking fluid near Youngstown after seismologists at Lamont-Doherty linked the well to a series of nearby earthquakes.
