Latest Climate of the Arctic Stories
Glacier and Ice-Sheet Melting, Sea-Ice Retreat and Coastal Erosion Expected as a Result. Temperature change in the Arctic is happening at a greater rate than other places in the Northern Hemisphere, and this is expected to continue in the future.
Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at the National Center for Atmospheric Research (NCAR) and Ohio State University. The study can help scientists improve computer models and determine if Earth's southernmost continent will warm significantly this century, a major research question because of Antarctica's potential impact on global sea-level rise.
The shrinking expanse of Arctic sea ice is increasingly vulnerable to summer sunshine, new research concludes. A new study finds that unusually sunny weather contributed to last summer's record loss of Arctic ice.
Arctic ice has reformed rapidly this winter after a record summer low, but it still covers less of the Arctic Ocean than it did in previous decades, NASA scientists announced today in an update of the states of Arctic and Antarctic sea ice. March is the month where Arctic sea ice traditionally hits its highest extent after the Northern Hemisphere winter and Antarctic sea ice reaches its lowest extent. NASA satellites have monitored sea ice coverage over both poles for nearly 40...
There's more to the recent dramatic and alarming thawing of the Arctic region than can be explained by man-made global warming alone, a new study found. Nature is pushing the Arctic to the edge, too.
Scientists have detected an ongoing reversal in Arctic Ocean circulation triggered by atmospheric conditions. The results suggest not all the large changes seen in Arctic climate in recent years are a result of long-term trends associated with global warming.
A new NASA-led study found a 23-percent loss in the extent of the Arctic's thick, year-round sea ice cover during the past two winters. This drastic reduction of perennial winter sea ice is the primary cause of this summer's fastest-ever sea ice retreat.
There was less sea ice in the Arctic on Friday than ever before on record, and the melting is continuing, the National Snow and Ice Data Center reported.
In 2006, Greenland experienced more days of melting snow and at higher altitudes than average over the past 18 years, according to a new NASA-funded project using satellite observations.
A new study by NASA scientists suggests that greenhouse-gas warming may raise average summer temperatures in the eastern United States nearly 10 degrees Fahrenheit by the 2080s.
