Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

Arctic Sea Ice Extent Breaks Record Low and Melting

Posted by feww on August 28, 2012

Northern Hemisphere Sea Ice Cover Falls to Record Low

Arctic sea ice extent shrank to 4.10 million square kilometers (1.58 million square miles) on August 26, 2012 and continued melting. The new record low was 70,000 km² below the September 18, 2007 daily extent of 4.17 million km², National Snow and Ice Data Center (NSIDC) reported.

FEWW model shows the Arctic sea ice extent could fall below 3.8 million km² during the 2012 melt season with a probability of 0.7 [P≥72%]
