New submitter turkeyfish writes "UK scientists are reporting today in the journal Nature Geoscience that a huge bulge of freshwater is forming in the Western Arctic Ocean caused by a large gyre of freshwater. The gyre appears to indicate that the ice is becoming thin enough over the Arctic Ocean that the wind is beginning to affect the motion of water under the ice. A sudden release of this water or its emergence to the surface will greatly accelerate the melting of the remaining polar oceanic ice and likely alter oceanic circulation in the North Atlantic."
