Wrangel Island ice bridge methodically becoming no more.

~If it all melts,  2012 extent record will be seriously challenged or exceeded

    Within last 4 days,  the Wrangel Island ice bridge has lost about half of its extent,  at this rate it should be all gone within a week,  since the water surface to ice ratio increases every day:

Once the middle of Wrangel Island ice bridge to Pole becomes water, likely in a few days if not tomorrow, the melting will accelerate.   Comparing to 2012 is of interest:

     There are huge differences between the icescape of August 27, 2016 and same day 2012.  2012 had an ice bridge to Wrangel but disappeared earlier,  North of Laptev sea ice was only present above 80 N,  the Atlantic front was more to the North.  However 2016 has a deeper towards the North Pole sea water bite and has incredible CAB lower density sea ice areas :

   The over all up to date review suggests 2016 capable of surpassing 2012 in its own way.    Melt years are rarely alike,  even one following another.  What makes 2016 apart,  is that it happened significantly without a prolonged Arctic Dipole,  in other words, without a great deal of summer insolation (and its cooler in summer when cloudy,  even in the Arctic).  This was a prerequisite proving that warming Global Temperatures need not have favourable weather conditions to devastate the existence of Arctic Sea ice.  WD August 28,2016
