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.
Records show that “when there is fuel on the landscape and you dry it out, then fire is inevitable,” Lamont's Park Williams says. His recent research explores the role of rising global temperatures.
Volcanic crystals can act like clocks, telling researchers how soon a volcano erupted after its last pulse of magma. Lamont's Terry Plank talks with Science about "crystal clocks" and measuring the speed of rising magma.
Researchers are studying the ocean's carbon dynamics to improve predictions for sea level and temperature rise. “New technologies are allowing us access to these remote areas, and we are far less dependent on driving a ship through the sea ice," Lamont oceanographer Arnold Gordon told Nature magazine.
Millions of people in Bangladesh are still being exposed to arsenic in their drinking water, decades after the problem was identified. The Lancet talks with Lamont's Lex van Geen about his work on arsenic in drinking water in South Asia.
To predict and prepare for future climate change, scientists are striving to understand how global-scale climatic change manifests itself on regional scales and also how societies adapt—or don’t—to sometimes subtle and complex climatic changes.These issues were at the heart of the inaugural workshop of the Volcanic Impacts on Climate and Society (VICS) Working Group, convened at Lamont-Doherty Earth Observatory.
Students from nine Rockland County high schools will get hands-on experience at land use planning at collaborative workshops with Columbia University's Lamont-Doherty Earth Observatory and Rockland Conservation Service Corps.
Almost all the world’s illegal ivory comes from elephants that have been recently killed, according to a new study from Lamont's Kevin Uno.
The illegal trade in elephant ivory is being fueled almost entirely by recently killed African elephants, not by tusks leaked from old government stockpiles, as had long been suspected. That’s the conclusion of a new study from Lamont's Kevin Uno that relies on nuclear bomb tests carried out in the 1950s and ’60s to date elephant tusks.
John Batchelor talks with Lamont's Peter de Menocal about the timing of when Homo sapiens began migrating from Africa.
The federal Bureau of Ocean Energy Management is compiling and updating maps and databases about offshore sediment resources from Maine to Florida for use in post-hurricane beach replenishment. The cores from those offshore deposits are now being kept at the Lamont Core Repository.
Lamont's Carlos Becerril talks with the New York Academy of Sciences about his team's work building ocean bottom seismometers as part of the Ocean Bottom Seismograph Instrument Pool (OBSIP).
A magnitude 6.6 earthquake struck Italy on Oct. 30 following two smaller earthquakes a few days earlier and a devastating earthquake there in August. “Probably it's every hundred years you get a repeat of a series of earthquakes,” Lamont's Michael Steckler told CBS News.
Looking ahead to looming water quantity shortfalls, Lamont's Yan Zheng argues that using reclaimed water for managed aquifer recharge needs to play a larger role in China’s water management strategies.
The wildfires that raged through the Western United States this year claimed lives, destroyed hundreds of homes and cost taxpayers millions of dollars. A new study from Columbia University's Park Williams has found that climate change has been exacerbating wildfires in the Western United States for decades.
U.S. and British science agencies announced a multimillion-dollar research mission to study Antarctica's enormous Thwaites Glacier, which could hold the potential for major sea level rise this century. Getting “up close and personal” with the glacier will help researchers close critical data and knowledge gaps, said Lamont's Robin Bell.
Lamont's carbon capture and storage project in Iceland that proved we could turn CO2 from a power plant to a solid mineral in a short period of time was listed among the greatest engineering innovations of 2016. The project was led by Juerg Matter and Martin Stute.
Lamont's Heather Savage will receive AGU's 2016 Mineral and Rock Physics Early Career Award at the 2016 American Geophysical Union Fall Meeting. The award is for promising young scientists in recognition of outstanding contributions achieved during their Ph.D. research.
