Two key climate change indicators—global surface temperatures and Arctic sea ice extent—have broken numerous records through the first half of 2016, according to NASA analyses of ground-based observations and satellite ...

The recent trend of increasing Antarctic sea ice extent—seemingly at odds with climate model projections—can largely be explained by a natural climate fluctuation, according to a new study led by the National Center for ...

By the 2050s, parts of the Arctic Ocean once covered by sea ice much of the year will see at least 60 days a year of open water, according to a new modeling study led by researchers at the University of Colorado Boulder.

Arctic sea ice extent plunged precipitously from 2001 to 2007, then barely budged between 2007 and 2013. Even in a warming world, researchers should expect such unusual periods of no change—and rapid change—at the world's ...

NASA satellite instruments have observed a marked increase in solar radiation absorbed in the Arctic since the year 2000 - a trend that aligns with the steady decrease in Arctic sea ice during the same period.

It comes as no surprise, therefore, when researchers announce as they did this past September that Arctic sea ice extent is still below normal, continuing a years-long downward trend, covering less and less of the north polar ...

New research suggests that Antarctic sea ice may not be expanding as fast as previously thought. A team of scientists say much of the increase measured for Southern Hemisphere sea ice could be due to a processing error in ...
