Shrinking Snowpacks Projected to Affect 2 Billion Lives in N. Hemisphere - International Business Times
A new study led by Lamont's Justin Mankin looking at the impact of shrinking snowpacks in the northern hemisphere suggests that over 2 billion people could suffer from water shortages.
Accurately measuring historic sea levels isn't easy. Lamont-Doherty's Maureen Raymo discusses some of the challenges.
Lamont scientist Conny Class and former Lamont post-doc Esteban Gazel scan islands off Panama for clues to how the country formed and its impact on ocean circulation.
All basins will likely have less water from snowpack as the planet warms, but some regions will be in worse shape than others. A new study led by Lamont-Doherty's Justin Mankin highlights 32 that are most at risk.
“The students are collecting data that is going to be shared with other students; this means that it has to be solid data. That puts an extra responsibility on them,” said Lamont Education Coordinator Margie Turrin. “So it's really mimicked what science is like — that it's done by a community of scientists.”
Yemen suffers back-to-back strikes as Cyclone Megh makes landfall just a week after Cyclone Chapala. Lamont's Suzana Camargo discusses potential El Nino connections to the extreme weather in the region.
A mighty river once coursed through what is now the Sahara Desert, one of the driest places in the world, new satellite images suggest. Lamont's Peter deMenocal says it's evidence that an entire region that lacks rainfall today once supported a large river system.
Tree ring chronologies from across Europe and the Mediterranean have been used to create a drought atlas of the Old World that reaches back more than 2,000 years. The atlas, led by Lamont's Ed Cook, is the third providing insights into the Northern Hemisphere, joining the North American Drought Atlas and Monsoon Asia Drought Atlas.
The new Old World Drought Atlas uses tree-rings to map droughts and periods of extreme rain through 2,000 years of European history. The project, led by Lamont's Ed Cook and involving dendrochronologists across Europe, joins drought atlases for North America and Asia to create a view of the Northern Hemisphere.
The Old World Drought Atlas, led by Lamont-Doherty's Ed Cook and based on thousands of tree ring samples, fills in details about past events and could help improve climate modeling for the future.
A new atlas based on tree ring research and led by Lamont-Doherty's Ed Cook of the Tree Ring Lab documents the reach of Europe's historic droughts in detail.
On Nov. 5, 1965, climate scientists summarized the risks associated with rising carbon pollution in a report for Lyndon Johnson. Lamont's Wally Broecker was among them.
In this short video, Lamont's Jason Smerdon explains connections between climate change and extreme weather.
Nature follows an expedition to study the fate of Antarctica's ice. The ROSETTA-Ice expedition includes the IcePod team led by Lamont-Doherty's Robin Bell.
In 1985, El Niño research pioneers Mark Cane and Steve Zebiak came up with the first computer model that successfully predicted the periodic Pacific Ocean warming event the following year. Thirty years later, models have improved, but El Niño remains elusive, says Lamont-Doherty's Cane.
Robin Bell: Science Is Like Running a Small Business, Where the Currency Is Ideas - Forecast Podcast
Science is like running a small business, where the currency is ideas, Lamont-Doherty's Robin Bell tells Michael White, Nature’s editor for climate science.
“The drying is coincident with a lot of major events in human evolution,” Lamont's Peter deMenocal said. It coincides with the appearance in the fossil record of the first members of the Homo genus, along with Paranthropus. Australopithecus disappeared around the same time.
For centuries, Rotterdam and Hamburg have had to contend with the threat of storm surges and floods. Now, as sea levels rise, planners are looking at innovative ways to make these cities more resilient. Quotes Lamont-Doherty's Klaus Jacob.
“We have to fundamentally rethink what it means to be a coastal city, and it depends on the geography of each city what then the possible solutions are,” Lamont's Klaus Jacob told the Christian Science Monitor.
Lamont scientists Colin Stark and Goram Ekstrom have detected a massive avalanche on one of Canada's highest mountains, a landslide that otherwise would have gone completely unnoticed in a remote part of northwestern Canada.
