World Meteorological Organization: "Average Arctic sea ice extent for November was the lowest on the satellite record, reflecting unusually high air temperatures, winds from the south, and a warm ocean. Antarctic sea ice extent quickly declined in November, also setting a record low for the month – in marked contrast to recent years. For the globe as a whole, sea ice cover was exceptionally low, according to the U.S. National Snow and Ice Data Center (NSIDC)."
