Arctic Sea Ice Loss is Impacting Atlantic Ocean Water Circulation System
New research from Yale University and the University of Southampton shows that the loss of Arctic sea ice is impacting the Atlantic Ocean water circulation…
New Study Shows Warmer Temperatures May Increase Emissions of Carbon Dioxide from Alaskan Tundra
A newly published study reveals that warmer temperatures and thawing soils may be driving an increase in emissions of carbon dioxide from Alaskan tundra to…
NASA Shows Arctic Sea Ice Is Losing Its Bulwark Against Warming Summers
New research shows that the Arctic sea ice has been hit with a double whammy over the past decades: as its extent shrunk, the oldest…
Yale Scientists Solve the Problem of Sea Ice Thickness Distribution
Using molecular concepts and treating the ice floes of the frozen seas like colliding molecules in a fluid or gas, researchers at Yale University have…
2015 Arctic Sea Ice Maximum Annual Extent is the Lowest on Record
Arctic sea ice has reached its peak winter extent for the year, and new data from the NASA-supported National Snow and Ice Data Center shows…
NASA Satellites Show Arctic Ocean is Absorbing More of the Sun’s Energy
Using data from NASA satellite instruments, astronomers have observed a marked increase in solar radiation absorbed in the Arctic since the year 2000 – a…
New ScienceCast Video: The Cloudy Future of Arctic Sea Ice

Shallow Undersea Methane Hydrate Deposit Found in Arctic
In the Arctic Circle, on the continental slope off Canada in the Beaufort Sea, the shallowest known deposit of methane hydrate has been discovered. The…
Carbon Locked in Arctic Permafrost Will Contribute to Global Warming
Fresh concerns are being expressed about the carbon locked in the Arctic’s permafrost. New studies presented at the American Geophysical Union quantify the amount of…
Low Arctic Snow Cover Could be Trouble for Permafrost
June Arctic snow cover in the Northern Hemisphere dropped by almost 18% per decade over the last 30 years. This drop in snow cover will…
Record Arctic Snow Melt Might Be Prolonging American Drought
While it may seem that melting arctic snow isn’t as dramatic as the record ice melt that’s occurred this year, the loss of arctic snow…
DARPA Program Takes Advantage of Floating Icebergs
