What’s Destroying the Arctic Sea Ice?

Here’s a piece on “heat bombs” that researchers believe are a chief cause of the vast Arctic ice-melt taking place before us.

Until now, it was known that all sea ice is on a path to disappear in the Arctic summers in the next few decades, but no one understood the mechanism by which this catastrophe is occurring. It is now clear that the warm highly saline waters entering from the Northern Pacific through the Bering Straight is subducted (pulled under) the surface due to its higher density than the cold, less salty waters that come from the Atlantic.  They form eddies (circular currents) called “heat bombs” that slowly mix as they rise to the surface.  Great video below.
