As polar night has covered the Arctic, it is supposed to be extremely cold there. But on the contrary, it is super-hot by polar standards, with temperatures hitting new highs.
“Today’s latest #Arctic mean temperature continues to move the wrong direction. . . up. Quite an anomalous spike!” said Zack Labe, a PhD student at the University of California at Irvine who studies the Arctic, on Twitter.
As temperature has increased to about 36 degrees Fahrenheit warmer than usual, the extent of sea ice has decreased.
