The image below, from The Cryosphere Today, shows that Arctic sea ice has shrunk in area by 11.446871 million square km from March 28, 2012, to September 11, 2012, a fall of over 83.66 percent in 167 days.
The image below illustrates the dramatic drop in sea ice extent (total area of at least 15% ice concentration) for the last 7 years, compared to the average 1972-2011, as calculated by the Polar View team at the University of Bremen, Germany.
