Greenland and its ice sheet have warmed briskly in recent years, and this summer has been warmer than normal. But in July’s final moments, at the apex of Greenland’s ice sheet, the mercury plunged to 23 degrees below zero (-30.7 Fahrenheit). Lamont's Marco Tedesco and other scientists explain why a short cold snap doesn't make a trend.
Vox Populi talks with Lamont's Peter deMenocal about an philanthropy raising funds for ocean science that's led by surfers.
Lamont's Adam Sobel explains that the lack of hurricanes making landfall in the U.S. in recent years is a relatively short-term fluctuation. The projections for increased storm intensity are for long-term global trends.
Scientists like Lamont's Suzanne Carbotte are tapping new technologies to unravel the mysteries of the deep.
Lamont's Marco Tedesco views the Arctic as a systems engineer would. He has been trying to “close the loop” and connect the exceedingly complex interactions that drive the northern climate system, which includes its sea ice, atmosphere and ocean circulations, and land ice.
In this audio podcast, Lamont's Hugh Ducklow, lead researcher for Antarctica's Palmer Station LTER, talks to The Explorers Club about the changing state of our polar regions.
Scientific American talks with Lamont's Marco Tedesco, who studies melting on Greenland, about a new project exploring how microorganisms help determine the pace of Arctic melting.
A new analysis of cyclone data and computer climate modeling, led by Lamont's Adam Sobel, Suzana Camargo, Allison Wing and Chia-Ying Lee, indicates that global warming is likely to intensify the destructive power of tropical storms.
In an Op/Ed article in the New York Times, Lamont's Adam Sobel explains why hurricanes are likely to become more intense with climate change and how recent history fits scientists' expectations.
A group of scientists studying a broad range of Arctic systems — from sea ice to permafrost to the Greenland ice sheet — gathered in D.C. to lay out just how extreme a year 2016 has been so far for the northern cap of the planet. “I see the situation as a train going downhill,” said Lamont's Marco Tedesco. “And the feedback mechanisms in the Arctic [are] the slope of your hill. And it gets harder and harder to stop it.”
The risk of rapid coastal subsidence to infrastructure and economies is global and is most acute in large river deltas, which are home to about 500 million people. An international community of researchers is calling attention to the need for better measurements and modeling and linking the science with its socioeconomic implications, Lamont's Michael Steckler and colleagues write.
A megathrust fault could be lurking underneath Myanmar, Bangladesh, and India, exposing millions of people to the risk of a major earthquake, according to research led by Lamont's Michael Steckler.
Lamont's Colin Stark visited the Glacier Bay landslide and said closer inspection revealed two big discoveries: the slide was still active days later, and the original landslide was so powerful it pushed rock and dirt up the sides of the valley almost 300 feet.
It's the second summer for the Biking While Breathing project which looks at the impact of air pollution on exercise in New York City. This year, researchers are considering going cheap. Cites Steve Chillrud's work.

Seismic recordings registered a massive landslide in Alaska's Glacier Bay National Park, and scientists are studying how the region's geology and environmental change are elevating the risk of mountain landslides. Cites work by Colin Stark and Göran Ekström.

More than 100 million tons of rock slid down a mountainside in Southeast Alaska on Tuesday morning, sending debris miles across a glacier below and a cloud of dust into the air. Lamont's Colin Stark and colleagues analyzed the landslide through its seismic waves.
Slowdowns of the Atlantic meridional overturning circulation have long been suspected as a cause of the climate swings during the last ice age, but never definitively shown, until now. The new study “is the best demonstration that this indeed happened,” says Lamont's Jerry McManus.
A new study led by Lamont's Ryan Abernathey shows how sea ice migration around Antarctica be more important for global ocean overturning circulation than previously thought. (In Spanish)
