During the record hot year of 2016, both Arctic and Antarctic sea ice extents took a huge hit.
Extreme warmth in the Arctic helped to produce leading losses there. Values that began during January at 1 million square kilometers below average have steadily declined as the months progressed to near 2 million square kilometers below average. Meanwhile, the Antarctic — which began the year at near average sea ice extent values — saw significant losses as the region grew anomalously warm during austral spring. Today, sea ice extent values surrounding the Antarctic are now also just shy of 2 million square kilometers below average.
(Zachary Labe, one of the most well-recognized up and coming U.S. climate scientists, has produced this graph based on NSIDC recorded global, Arctic, and Antarctic sea ice values. As you can see, global sea ice extent during the hottest year on record has steadily plummeted…
