Arctic Sea Ice Extent Down to 3.87M km² and Melting

Northern Hemisphere Sea Ice Cover Continues Shrinking

Arctic sea ice extent shrank to about 3.87 million square kilometers (1.49 million square miles) on August 29, 2012 and continued melting, FIRE-EARTH estimates. The new record low was 100,000 km² below the September 18, 2007 daily extent of 4.17 million km².

FEWW model shows the Arctic sea ice extent could fall below 3.8 million km² during the 2012 melt season with a probability of 0.8 [P≥77%]
