A new study from Lamont's Peter deMenocal and colleagues finds the Horn of Africa is drying and will continue to get drier. That's likely to drive poverty and piracy.
Evidence stretching back 40,000 years shows that global warming will increase drying in a region of East Africa where drought already causes humanitarian crises. Cites research by Lamont-Doherty's Peter deMenocal.
Lamont's Joaquim Goes and Helga do Rosario Gomes have been studying blooms in the Arabian Sea, where a tiny organism and its tenants have made an unexpected appearance that could harm other marine life that the region depends on for food.
Hurricane-force winds remove large amounts of snow in Antarctica, which might increase the estimates of how much the frozen continent contributes to sea level rise. Cites research by Lamont-Doherty's Indrani Das.
The Horn of Africa is warming and drying faster now than in the past 2,000 years, says new research into ancient marine sediments found. The findings contradict global climate models, which show that the geopolitically unstable region getting wetter as emissions boost temperatures worldwide, says Lamont's Peter DeMenocal.
Lamont-Doherty's Nicolas Young was named a winner of the 2015 Blavatnik Regional Awards, given to post-doctoral scientists and affiliated with the New York Academy of Sciences. “These talented young scientists will continue to foster innovation and new discoveries for years to come,” said Len Blavatnik, head of the Blavatnik Family Foundation.
Recent figures reveal that the number of Ethiopians in need of food has risen sharply because of the lack of rain, combined with the El Nino weather phenomenon. A new study involving Lamont-Doherty's Peter deMenocal suggests that the region is growing drier.
The already arid countries of Djibouti, Ethiopia and Somalia are becoming even drier at an unusually fast pace, threatening to deepen drought, famine and instability, a new study by Lamont-Doherty's Peter DeMenocal and former post-doc Jessica Tierney finds.
The Horn of Africa is becoming drier in step with global warming, researchers said on Friday, contradicting some climate models predicting rainier weather patterns in politically challenged region. Cites research by Lamont's Peter DeMenocal and former post-doc Jessica Tierney.
The Horn of Africa is growing drier, threatening food security for millions of people — and this change is driven by global warming, according to an analysis from Lamont-Doherty's Peter deMenocal.
Lamont-Doherty's Robin Bell talks with WNET for American Graduate Day about her work on glaciers, the IcePod project and what inspired her to become a scientist.
About 73,000 years ago a volcano collapsed. Its force generated a wave that engulfed an island over 30 miles away. Cites research by Lamont-Doherty's Ricardo Ramalho and Gisela Winckler.
The evidence hinges on the nature of the boulders, which are composed of rock types that "exclusively crop out on the cliff faces and lower slopes of the plateau, implying a source at considerably lower elevations," the authors write. Richard Ramalho worked on the study at Lamont-Doherty.
"Most of these fairly young oceanic volcanoes—such as in the Azores and the Canary Islands and Hawaii—are incredibly high and steep, so the potential energy for a collapse to happen again is there,"said Richard Ramalho, who worked on the study at Lamont-Doherty Earth Observatory.
Geologists have concluded that 73,000 years ago, a tsunami six times taller than the wave that hit Japan in 2011 struck off the coast of West Africa, in the Cape Verde islands. Cites work by Gisela Winckler and Ricardo Ramalho.
Catastrophic wildfires in the West are burning land more violently and more frequently in recent years than at any point on record. Lamont-Doherty's Park Williams explains how this year’s big fires have corresponded with higher temperatures.
Lamont-Doherty scientists Linda Heusser and Jonathan Nichols used ancient pollen to look at Southern California's changing ecology through time and discovered a series of mega-droughts thousands of years ago.
With Hurricane Joaquin headed northward in the Atlantic, the Wall Street Journal looked at how prepared the New York City subway system is to handle another major storm. The Journal spoke with Lamont-Doherty's Adam Sobel.
Scientists warn that a similar event to the collapse of a volcano on the Cape Verde island of Fogo 73,000 years ago could pose major threats to nearby islands. Cites research by Ricardo Ramalho.
Geologists tend to notice when big rocks are out of place, like the elephant-sized chunks of basalt and limestone that had formed at sea level and somehow ended up more than six hundred feet above, on a volcanic plateau on Santiago Island. Cites research by Ricardo Ramalho.
