NSIDC: April Arctic Sea Ice Extent Second Lowest on Record


The National Snow and Ice Data Center has released its analysis of Arctic and Antarctic sea ice for April 2014

Arctic sea ice extent for April 2015 averaged 14.0 million square kilometers (5.4 million square miles), the second lowest April ice extent in the satellite record. It is 810,000 square kilometers (313,000 square miles) below the 1981 to 2010 long-term average of 15.0 million square kilometers (6.0 million square miles) and 80,000 square kilometers (31,000 square miles) above the previous record low for the month observed in 2007.

NSIDC reports that most of the arctic was 1 to 3 degrees celsius above average temperature,   and that the sea ice is continuing to decline at a rate of approximately 2.4% per decade.
