Image of the Day: Artistic Ice Waves off Greenland

A view of fjords on the southeastern coast of Greenland funneling glacial ice into the Atlantic Ocean. According to the U.S. Geological Survey, during the summer melting season, the southward-flowing East Greenland Current occasionally swirls the newly calved icebergs, as they join with sea ice and preexisting icebergs, into stunning shapes.

With about a month and a half remaining in this Arctic melt season, sea ice cover continues to decline at a rapid pace, and is currently on par with where the 2007 record melt season stood at the same time of year. Arctic sea ice extent has been declining at a rate of about 12 percent per decade since the start of satellite measurements in 1979, and a new study suggests that natural climate variability explains some, but not the majority, of this trend. The study concludes that manmade global warming is the most plausible explanation for recent sea ice decline.
