6 years later, what about 80 degrees North?

~2012 all time minima melt is on the brink of being surpassed
~In fact 2012 Central Arctic Basin is almost the same as 2018
~What is left is not what matters,  what matters is at 80 degrees North

To date,  Canadian Arctic Archipelago has 250,000 Km2 more sea ice than 2012,  strangely,  given the onslaught of broken sea ice which invaded the area, Beaufort sea has the same extent,  but East Siberian has another 250,000 Km2 more.  What is left is the Central Arctic Basin,  with 2018 having slightly less sea ice extent than 2012.  The colours which matter on the following AMSR2 Google graphs are orange 2012,  olive green 2016 and black 2018:

   All said and done,  today 2018 is still technically #1 in lowest extent since East Siberian and CAA ice will at least shrink by 400,000 km2 come minima in mid September.  Today was the 2012 great cyclone anniversary date,  which violently stirred and mixed up already emaciated sea ice,  lets look at 80 degrees North:

     80 degrees North 157 West  is in worse shape in 2018, what matters is the greater open water signifying greater melting,  2012 had more thin ice left.  Again,  the measuring limitations given by the 15% extent rule may not show a great difference in extent numbers between these two seasons.   Nevertheless,  this type of sea ice rot emplies East Siberian sea will be eventually surrounded by open water, easing the quicker melting of the ice peninsula further to its North .  The quicker this ice   disappears the more certain 2018 will be #1 lowest.  WD August 5 2018
