Climate Progress – NASA explains how Europe can be so cold amidst the hottest November and hottest year on record

How did we get record-breaking November warmth in the middle of a strong La Niña that would normally cool global temperatures (as it did in the fall of 1998, see lower right figure, blue line)? Is the answer the Arctic sea ice death spiral 2010? And is the loss of Arctic sea ice also responsible for the frigid European temperatures?
NASA’s James Hansen, Reto Ruedy, Makiko Sato and Ken Lo answer these questions in “2010 — Global Temperature and Europe’s Frigid Air,” which I repost below with the original figures:
