Northern Hemisphere sea ice extent in December 2010 was the lowest in the 31-year satellite record, according to the National Snow and Ice Data Center. Ice volume in December was also the lowest on record for this time of year, according to University of Washington Polar Ice Center. At the end of December, the eastern portion of Canada's Hudson Bay remained unfrozen, the first time in recorded history that Hudson Bay has not been completely frozen over at the end of the year. The unusual amount of open water led to temperatures that averaged 20 °C (36 °F) above normal over a region larger than Texas during the first ten days of January.
