New research from Lamont's Adam Sobel and alumnus Solomon Hsiang suggests that even a moderate amount of warming could force populations in the tropics to undergo huge migrations — longer journeys than they would have to take if they lived anywhere else on the planet.
New research led by Lamont's Marco Tedesco links Greenland's 2015 record temperatures and melting with the phenomenon known as Arctic amplification.
As Arctic sea ice hit a record low, scientists led by Lamont's Marco Tedesco announced the first link between melting ice in Greenland and a phenomenon known as Arctic amplification, the faster warming of the Arctic compared to the rest of the Northern Hemisphere.
The pioneering maps put together by Lamont's Marie Tharp and Bruce Heezen in the 1950s and 1960s, which first identified the structure of the mid-Atlantic ridge, were mind-expandingly right in their synoptic vision. The Economist looks at the challenges then and now of mapping the sea floor.
Lamont's Joerg Schaefer answers a reader's science question for the New York Times: Was there an ice age in the Southern Hemisphere?
A team of Lamont researchers led by Christine McCarthy has built a new apparatus in the Rock Mechanics Lab to gain insight into the behavior of ice on Earth and elsewhere in the solar system.
Earth Magazine talks with Suzanne Carbotte and other scientists about advances in the mapping of the seafloor that are providing extraordinary detail.
Scientists led by Lamont's Beizhan Yan have discovered the mechanism that transported contaminants from the Deepwater Horizon oil spill to the bottom of the Gulf of Mexico.
Researchers led by Lamont's Beizhan Yan estimate that 10 to 15 percent of the oil released by the Deepwater Horizon disaster sank to the seabed in the Gulf of Mexico, where it covered hundreds of square miles. (In German)
A new study led by Lamont's Christine McCarthy offers a glimpse of what happens inside ice. The scientists developed a device to measure ice as it changes in response to external forces, both on Earth and on the moons of other planets.
Was that extreme weather event caused by climate change? It’s a question scientists get asked a lot, and one that they’re increasingly able to answer, says Lamont's Adam Sobel.
In this podcast, Lamont's Christine McCarthy talks about life and the science of flowing ice.
The wreckage from EgyptAir Flight 804 is likely in the Mediterranean Sea somewhere between Crete and Egypt. Lamont's David Gallo discusses the challenges of the search.
The flight’s track indicated that it crashed about halfway between Crete and Egypt. “If that is correct, then it has landed on a feature we call the Mediterranean Ridge,” Lamont's Bill Ryan told the Times. When sonar is used to scan the area, “you get a complex play of echoes that was nicknamed cobblestone, showing the sea floor is very bumpy."
The Totten glacier ice region is bigger than California, and could raise seas by over 10 feet if it collapsed. The Washington Post talked with scientists, including Lamont's Robin Bell, about the risks.
Cedar trees living on the steep cliffs of the Niagara Escarpment were centuries old, and no one knew until scientists took a closer look. The Tree Ring Lab at Lamont confirmed their find.
In this short video podcast, Huffington Post's Karah Preiss and Lamont professor Peter de Menocal discuss the historical epochs, the idea of the Anthropocene, and whether it’s possible to change course.
One of the best-established ideas about global warming is that it will hit the Arctic the hardest, creating a feedback loop as melting ice leaves more dark ocean to absorb more energy. It's part of a concept called “Arctic amplification." Already this year, the Arctic has exceeded 4 degrees Celsius above average. Chris Mooney discussed the changes with Lamont's Marco Tedesco.
Scientists have discovered a major problem with one popular geoengineering scheme that entails dumping iron into the ocean to fuel algae that can soak up carbon dioxide: Basically, the plan is not supported by the geologic record, at least not in the equatorial Pacific. The study was led by Lamont's Gisela Winckler and Robert Anderson.
The first global digital-elevation model of Mercury reveals a striking landscape of basins and lava plains. Lamont Director Sean Solomon was principal investigator on the MESSENGER mission and discussed the data MESSENGER captured.
