Massive off Axel Heiberg and Ellesmere "Big Lead" event just occurred

~Unusual since it is not moon related
~A sudden apparently surface wind easily broke up a once consolidated multi-year sea ice with ease

The thickest strongest Sea ice is getting pulverized quickly,  mainly by consistent North of Greenland high pressure giving clockwise winds,  with other factors such as tides.   Reminiscent of 2016 action,  or March 1989,  but the latter was related to massive synergistic tidal forcing under very frozen sea icescape.  2020 June 26, 27 and 28 action was unequally caused by melted snow accelerating true ice surface melting.  This event appears highly regionalized,  suggesting a rather poor consolidated state of sea ice everywhere else.  WD June 28, 2020

Atlantic Front sea ice collapsing

~With top of sea ice snow curtain melted,  the status at the Atlantic Front is revealed
~It is broken up ,  ready to move anywhere, at the winds whim

    Deep past the Atlantic ice front between Spitzbergen and Franz Josef Islands lies a state of loose pack ice, ready for the clearing,  only if the winds team up with the sea current.  And so it is just a matter of synergistic coincidence as to whether a massive melt will show at end of September.  NASA EOSDIS June 20-23 2020 loop  depicts a rather unsteady flow, moving one way one day,  the opposite direction the next. Once a certain towards the South wind pattern hits this region for about 1 week,  the clearing will be done.  leaving sea ice even further towards the Pole more vulnerable. 
The survival of 2020 sea ice is rather precarious at this moment.  WD June 24,2020

Jupiter has Arctic sea ice "Goodbye Waves" , the red version

~Geophysics can be filled with symmetrical effects,  some having same or wildly differing causes
~Arctic Goodbye waves,  seen here:  , are a terribly photogenic,  even artistic expressions from sea ice melting away. 
~But Jupiter is no Earth.  Or is there solids on top of its dense gaseous atmosphere?

    Thanks "New Horizons"  view here. Something on Jupiter looks familiar?  EH2r has dealt with this before:

  Although Jupiter is much more colourful,  the look is pretty much the same.  Here we can offer what is happening on top of Jupiter's dense (almost liquid?)  atmosphere.  "Goodbye Waves"  were once majestic sea ice just about vanished by melting,  leaving a trail of salts, biomass and fresh water not readily mixing with Arctic sea water,  but carried by sea currents giving the stylish twists and turns only found where there is an interface exposing the physics of two differing layers not readily intermixing.  2020 sea ice melt season will be great and perhaps will offer other planetary looks,  spectacular but too much of it is pretty bad from always pretty planet Earth.  WD June 15 2020

Assessing the impossible by other means; 2020 has a faster snow melting pace.

~A careful look at Northern Greenland and Ellesmere reveals the early melting pace
~2019-2020 was a winter with lots of snow
~Most of it gone where it should have been remaining,  that is if you look at surface temperatures and sea ice extent numbers.
~The mystery white mask of 2020 season is melting/sublimating away

   The first thing we remember about 2012 sea ice melt season,  was the cyclone over the Arctic Ocean on August 5.  But 2012 was also a year with a more normal snow cover as opposed to 2020.
The thing about Arctic snow over ice and land is that it is spread out quite evenly by the winds which may span in the same direction for hundreds of Kilometres. 2020 spread out was more important, by about a factor of 2 compared to 2012.   So you might think,  2012, the year with greatest sea ice melt on record should show more land than any other known year at an early melt season date,  say June 3:

NASA EOSDIS June 3 animation for years 2012 to 2020.  We see mainly  Ellesmere Island and a bit of Northeast Greenland,  the perineal coldest area of the Northern Hemisphere, doesn't quite matter which month you may chose.  Turns out 2012,  the year with less winter/spring snow precipitation, has more snow than 2020 on same June 3.   This is a very significant finding.  Less snow on ground means less fog or low clouds as well, 2012 shows that,  unlike cloudier 2020 still in progress of melting a once thicker snow carpet.  All the other June 3's from 2013 to 2019,  had over all significantly more snow coverage.

   The 2012 2020 comparison leaves no doubt about current faster snow melting, despite a cloudier 2020 late Spring.  WD June 5 2020
