Video: North Pole shrinks to record levels, could be gone in 4 years

 

This animation shows the 2012 time-series of ice extent. The black area represents the daily average (median) sea ice from 1979-2000. Layered over are the daily satellite measurements from January 1 — September 14, 2012. A rapid melt begins in July, whereby the 2012 ice extents fall far below the historical average.

 

This melting has caused many to reconsider their predictions. A Cambridge scientist in the Arctic believes we could be only 4 years from a North Pole without ice.

From Yale’s Environment 360:

Peter Wadhams, who heads the Polar Ocean Physics Group at the University of Cambridge and who has measured Arctic Ocean ice thickness from British Navy submarines, says that earlier calculations about Arctic sea ice loss have grossly underestimated how rapidly the ice is disappearing. He believes that the Arctic is likely to become ice-free before 2020 and possibly as early as 2015 or 2016 — decades ahead of projections made just a few years ago.
