Arctic ice cover can vary quite a bit from year to year, and this year&#8217;s weather did encourage melting. There were unusually clear skies, warm winds from the south, and winds and currents moved ice out of the Arctic Ocean next to Greenland. But natural variations don&#8217;t account for the huge magnitude of the drop. Global warming is the primary cause of this year\u2019s record low sea ice, as well as the significant decreases over the past few decades &#8211; that much is clear. But scientists still aren&#8217;t sure why the ice cover is shrinking so much faster than predicted.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The author of today&#8217;s post, Sheryl Canter, is an Online Writer and Editorial Manager at Environmental Defense.
