3. Sea Ice Extent
Arctic sea ice extent averaged for September 2012 was 3.61 million square kilometers. This was 3.43
million square kilometers below the 1979 to 2000 average extent. September 2012 ice extent was
690,000 square kilometers less than the previous record low for the month that occurred in 2007
