Impact of Large-Scale Tree Death on Carbon Storage Shown
Large-scale ‘disturbances’, including fires, harvesting, windstorms and insect outbreaks, which kill large patches of forest, are responsible for more than a tenth of tree death…

Arctic Sea-Ice Loss Has ‘Minimal Influence’ on Severe Cold Winter Weather
The dramatic loss of Arctic sea ice through climate change has only a “minimal influence” on severe cold winter weather across Asia and North America,…
Warmer Water Now Reaches Deep Into The Arctic Interior
Arctic sea ice isn’t just threatened by the melting of ice around its edges, a new study has found: Warmer water that originated hundreds of…
Arctic Boreal Vulnerability Experiment Shows Arctic Carbon Cycle is Speeding Up
When people think of the Arctic, snow, ice and polar bears come to mind. Trees? Not so much. At least not yet. A new NASA-led…
Arctic Sea Ice a Spring Hazard for North Atlantic Ships
More Arctic sea ice is entering the North Atlantic Ocean than before, making it increasingly dangerous for ships to navigate those waters in late spring,…
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
A new four minute ScienceCast video explores the shrinking coverage of Arctic sea ice and how the reduction could affect worldwide weather. ScienceCasts: The Cloudy…
Arctic Melt Season is Lengthening by Several Days Each Decade
A new study by NSIDC and NASA researchers reveals that length of the melt season for Arctic sea ice is growing by several days each…
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
If the Arctic continues to melt, there could be more military and commercial activity in this environment. DARPA is working on an all-seeing network of…
