Greenland's glaciers are on retreat, shrinking at strikingly fast rates -- at least twice as fast as any time over the last 9,500 years, according to new research for Lamont-Doherty's William D'Andrea.
People in Somaliland are losing everything as their land dries because of climate change. Cites research by Peter deMenocal showing dry conditions in the Horn of Africa are likely to get worse.
The effect of warming temperatures on farmland and water supplies wasn't the sole cause of conflict, but it definitely made the situation in Syria worse, write Lamont's Richard Seager, Mark Cane, and Yochanan Kushnir.
New geological data analyzed by Lamont's Nicolas Young and Joerg Schaefer on the extent of glaciers in the region at the time show that during the era when the Norse occupied the area, glaciers were almost as far advanced as they were during the subsequent Little Ice Age.
Evidence from glacial deposits analyzed by Lamont's Nicolas Young and Joerg Schaefer adds a new twist to the tale of the mysterious lost settlements of Greenland.
Erik the Red's colonization of Greenland did not come to an end because of falling temperatures, according to a new study by Lamont's Nicolas Young and Joerg Schaefer. They find that Greenland was already pretty cold when the Vikings arrived, suggesting that the Medieval Warm Period wasn't uniform around the globe.
As world leaders in Paris negotiate cuts in greenhouse gases, scientists say we face urgent reasons to take action. Lamont-Doherty's Jason Smerdon and Peter deMenocal talk about glacier loss and the destabilizing effects of climate change.
Three years after Superstorm Sandy, New York City is preparing for the dual threat of rising sea levels and another big storm. But are planners going far enough to keep nature at bay? Lamont's Klaus Jacob weighs in.
If clean energy became less costly to produce than energy based on coal, gas or oil, then coal, gas and oil would simply stay in the ground, the author writes. The big question is how to make it cheaper. Quotes Lamont's Richard Seager about the costs of climate change.
The rising number of cyclones in the Arabian Sea put the low-lying city of Mumbai at risk. Emergency planning is crucial, writes Lamont-Doherty's Adam Sobel.
Hordes of tiny zooplankton rise from the depths every night to feed, in the largest animal migration on Earth, writes Lamont's Kyle Frischkorn.
While world leaders discuss climate change in Paris this week, the humanitarian risks of disrupted weather patterns are fast becoming a reality in Africa. Quotes Lamont's Richard Seager describing how global warming adds to existing stressors.
In this BBC interview, Lamont-Doherty's Dennis Kent talks about Earth's changing magnetic field and where it may be headed.
The northern lights are shifting south from the Arctic, and will appear more often in the skies over Ottawa in decades to come, Lamont's Dennis Kent tells Canada's National Post. The reason: Earth’s magnetic field is becoming gradually weaker, and this affects how the solar wind — charged particles from the sun — bounces off it.
Over the past couple of hundred years, the strength of the Earth’s geomagnetic field has been waning, leading scientists to wonder if our planet’s polarity is on the verge of flipping. New research by Lamont-Doherty's Dennis Kent puts the dip into perspective.
Earth is not heading toward a reversal of its magnetic field any time soon, new research from Lamont-Doherty's Dennis Kent assures. While weakening, Earth’s magnetic field is still quite strong by historical standards.
The Seismological Society of America will present its highest honor, the Harry Fielding Reid Medal, to Lamont-Doherty's Christopher H. Scholz this spring.
The demand for energy around the world continues to grow each year. And so does the amount of carbon dioxide that's pumped into the earth's atmosphere. Lamont's Peter Kelemen explains in this podcast.
As global warming brings about a decline in snowpacks around the world, billions of people face a high risk of shrinking water supplies in the coming century, a study by Lamont-Doherty's Justin Mankin finds.
The links between climate change and severe weather are not as simple as blaming a severe storm on a warming planet, as Lamont-Doherty's Jason Smerdon explains.
