Gavin Shmidt @ NASA: "Warming Does Not Care About The Election"

EDIT

Climatologists actually predicted this latest “jump” in global temperatures. There is “a vast and growing body of research,” Climate Central explained in February 2015, indicating that “humanity is about to experience a historically unprecedented spike in temperatures.” One 2015 study concluded that we could even see Arctic warming rise an alarming 1°F (0.56°C) per decade by the next decade.

Speaking of the Arctic, look again at the top map from NASA. Large parts of the Arctic super-heated in October, as much 15.6 6°F (8.7°C) above the 1951–1980 mean temperature. No surprise, then, that last month saw the lowest October ice extent on record and that “as of November 1, sea ice volume is lowest on record.”

Recent research finds that rapid Arctic warming and sea ice loss are already worsening extreme weather. Amplified warming also means that the rapidly melting Greenland ice sheet, which is already unstable, will disintegrate even faster, boosting sea level rise more than previously estimated, upwards of six feet this century.

Finally, our current period of rapid Arctic warming sea ice loss threatens to speed up the release of vast amounts of carbon from thawing permafrost. This dangerous amplifying feedback alone could add as much as 1.5°F (0.8°C) to total planetary warming this century.
