Scientists are expected to announce that 2016 was the hottest year on Earth since record-keeping began in 1880 — news that will test national, state and economic leadership on climate change. “The climate system gives not a hoot about politicians in Washington denying the reality of human-driven climate change — but it does respond to decisions on energy, fuels and the environment those politicians make,” Lamont's Richard Seager said.
Greenland's Petermann Ice Shelf has lost huge ice islands since 2010. The question is no longer whether it is changing — it’s how fast it could give up still more ice to the seas. Chris Mooney talks with scientists, including Lamont's Marco Tedesco, about what they're seeing.
The Lamont-operated R/V Marcus G. Langseth is in Chile with teams of scientists studying the region's offshore seismicity. El Mercurio wrote about the work as a magnitude 7.7 earthquake struck off the Chilean coast. The article is in Spanish.
Researchers including Lamont's Paul Richards say a 2010 event previously thought to be a small nuclear test in North Korea was actually just a small earthquake – a finding that could have implications for monitoring the regime's nuclear tests.
A new report by seismologists from Columbia University's Lamont-Doherty Earth Observatory concluded that the tremors were much more like that of an earthquake than an explosion.
What will it take to bring true equity to research labs? Science Friday talks with Lamont's Kuheli Dutt and others (segment begins at 17:40).
By tracking heat-induced chemical signatures, researchers can determine where an earthquake began and ended, using a method created by Lamont scientists Heather Savage and Pratigya Polissar.
A new climate change app created by scientists at Lamont uses interactive data maps to engage users and prompt the exploration of questions related to changing sea levels and climate vulnerability.
Lamont Professor Peter Kelemen breaks down the process of oil formation.
Lamont grad student Josh Maurer has used images taken by Cold War spy satellites to reveal dramatic environmental changes occurring in the Himalayas.
Scientists issue their 2016 Arctic Report Card finding that the Arctic as a whole is warming at least twice as fast as the rest of the planet, and it is getting progressively worse. The cause of the warming is in part due to feedback loops, as Lamont's Marco Tedesco explains.
Fifty years ago, scientists began to connect details of an idea with profound implications: Earth's ocean crust recycles itself on a global scale, and continents move across the face of the planet. Scientists from Lamont brought the key evidence together.
Since the discovery by Lamont's Göran Ekström and Meredith Nettles of glacial earthquakes caused by Greenland’s short-term ice movements, the flourishing field of cryoseismology has proved to be a powerful tool for studying a variety of glaciological phenomena, including crevasse formation, basal shear sources, iceberg calving, the rifting process in ice shelves, sea ice dynamics, precursory signs of unstable glaciers in real time, and beyond.
Evidence buried in Greenland's bedrock shows the island's massive ice sheet melted nearly completely at least once in the last 2.6 million years. The findings from a study led by Lamont's Joerg Schaefer suggest that Greenland's ice may be less stable than previously believed.
A new study from Lamont's Joerg Schaefer published in the journal Nature undercuts key assumptions about Greenland's ice sheet, suggesting it may not be as stable as previously believed.
A new study led by Lamont's Joerg Schaefer indicates that the bedrock at the bottom of Greenland may not have been covered with ice for hundreds of thousands of years during the recent geological past. It's a finding that, if true, holds huge implications for coastal cities all around the world.
As the southern continent rapidly warms, some whale populations are booming—while others are suffering from lack of ice. National Geographic talks with Lamont's Doug Martinson.
Tornado outbreaks have become more extreme in recent decades, potentially related to climate change, but not for the expected reasons, according to a new study from Lamont's Chiara Lepore.
New research by an international team, including scientists from Lamont-Doherty Earth Observatory, shows that the present thinning and retreat of Pine Island Glacier in West Antarctica is part of a climatically forced trend that was triggered around the 1940s. Even when climate forcing weakened, ice-sheet retreat continued, the scientists found.
Wildfires have burned more than 100,000 acres across seven states since late October in the southern Appalachian Mountains, typically a wet region. NewsHour talked with Lamont's Park Williams, who said conditions at the epicenter of the drought rivaled conditions typically witnessed in the American West.
