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.
In a new study, Lamont's Park Williams estimates that human-caused climate change was responsible for nearly doubling the forest area that burned in the Western U.S. between 1984 and 2015. If the last few decades had been simply dry, instead of some of the hottest and driest on record, perhaps 10.4 million fewer acres would have burned, he says.
A new study of letters of recommendation written for post-doctoral scientists found that professors were twice as likely to write glowing letters of recommendation, as opposed to letters reflecting a merely good candidate, for men compared to women. The study was led by Lamont's Kuheli Dutt.
The Columbia Spectator talks with Lamont geologist Peter Kelemen about his career, climate change, and climbing.
Deep in the Altai mountains, scientists are using drones and chemistry to study glacier-formed ridges that could help unlock the mysteries of abrupt climate change. Lamont's Adjunct Associate Research Professor Aaron Putnam and Lamont Research Professor Joerg Schaefer describe their work to Pacific Standard.
The shrinking of Greenland’s ice sheet is triggering feedback loops that accelerate the global crisis. Elizabeth Kolbert cites research by Lamont's Marco Tedesco.
The U.S. Drought Monitor has placed Rockland County under a "severe drought." Rockland’s water sources are also stressed by an ever increasing population and lack of available space for new places to store water, making the county more vulnerable to short periods of decreased rainfall, said Lamont's Nicholas Christie-Blick.
Using ancient leaves, Lamont's Tammo Reichgelt and Billy D'Andrea have found evidence of a CO2 spike at the time 23 million years ago when Antarctica's ice sheet began to melt.
The American Geophysical Union's 2016 election results are in. Among the incoming AGU leaders are Lamont's Robin Bell (president-elect), Kerstin Lehnert (director), and Robert F. Anderson (ocean sciences president-elect).
Climate change from human activity nearly doubled the area that burned in forest fires in the American West over the past 30 years, a major new scientific study by Lamont's Park Williams has found. Larger, more intense fires are all but guaranteed in the years ahead.
A study by Lamont's Park Williams found that anthropogenic climate change was responsible for just over half of the total observed increase in fuel dryness since 1979. In turn, this influence has added more than 16,000 square miles of forest fire area to the western United States since 1984, nearly doubling the area scientists might have expected without the influence of similar climate change.
