Arctic unseasonably warm

Washington Post -While much of the Northeast was forced to batten down the hatches this week against strong winds, heavy snow and other icy conditions, the usually frigid Arctic experienced the opposite — a period of unseasonably mild weather and high temperatures, for at least the third time this winter... Data from the Danish Meteorological Institute suggests that, as of Thursday, temperatures in the area above 80 degrees north latitude were already more than 20 degrees warmer than the average temperature for this time of year.
