3.3 Polar sea ice

The ice around the North Pole is going away, and it’s doing so with alarming rapidity.  We are not talking about the yearly cycle of melt in the summer and freeze in the winter, but the long-term trend of declining amounts of ice. The area of the ocean covered by ice, as well  as volume, and the thickness of the ice is going down. Fast.
