Don't look UP .... North....... Arctic sea ice in dire straits (literally)

 ~Ridging sea ice against the Canadian Arctic Archipelago hardly exists!

   These are strange days, when denialists and a few microphone Youtube presenters sway large segments of our population to believe in fantasy impressions of reality,  even when evidence,  not little bit of evidence, massive sways of archives occupy computer memory banks, instead of human minds.  

  To help up a few hesitant deniers,  and to encourage them to do their own exploration, hopefully backed the writings of giants (found in any good science book) .  Here is the Canadian Arctic Archipelago,  just NW  of its center,  January 23 and below this for good measure 26 ,  2022,  

    January 23 Polarview picture,  the top one,  looks very distressing,  January 26 ,  same area,  shows some freezing,  which should be extremely strong in Polar darkness,  it doesn't seem so here.  For those who don't know about the Canadian Arctic Archipelago (ie CAA),  I am not surprised,  TV maps rarely depict them correctly:

The placement of 2021/22 on this weather map,  is where the sea ice pictures above come from.   The CAA is portrayed the usual way here,  as something to type over.  Actually its a fairly good TV weather map compared to most.    At any rate,  there was and  is (to a lesser extent) a tidal ridging of sea ice ,  going back millions of years, from the Arctic Ocean basin (the Arctic Ocean) towards the Canadian Arctic Archipelago NW shore,  this ridging and compaction, was, once upon a time ,  intense:

Same location as pictures above, HRPT likely USSR  Meteor,  but can be NOAA,  circa 1989, January 4.  The coastal Arctic sea ice day, was solidly frozen, marked by "tidal' leads, often frozen in a day, looking like hair strands or river channels.  On occasion, as on this day,  a High pressure, massive, heavy, opened up the very thick consolidated sea ice. But water opening never lasted longer than a few days, recognizable by their grey-ish appearance (new ice and fresh snow cover), the big black lead above  had a short lifespan.  Again for good measure we have another archive  picture:

     19 days later,  the huge High  pressure lead can't be recognized,  it almost totally vanished,  but newer "tidal" leads can be seen.     They are created  and destroyed, vanished  and faded daily.  The difference here,  between 1989 and 2022 is obvious,  there is less thick sea ice ridging against the CAA shores,  the 2022 shots demonstrate a summer sea ice configuration,  looser pack,  significantly thinner,  with a lot more open water.  Compare again with a modern same resolution as 1989 NOAA HRPT photo Jan 27 2022:

        Arctic long night sea ice is barely recognizable a mere 33 years later.WD Jan 28 2022

Great Temperate zone in origin FREEZING blast, whatever happened to the Arctic blast? I wonder.....


Last I looked , 65 degrees North latitude was the sub-Arctic,  where most of the cooling action seems to have been created in between January 5 and 10 2022,  but again, the greatest cooling occurred nearly in the temperate North American  zone.    In such the new weather Climate takes shape,  tropospheric Polar Vortex Cold Temperature North Pole vortices form here and there, appear to move rapidly,   or  form and disappear just as quickly,  at the same time, with very steady cyclones and jet stream positions.  And such are the days of transition,  just prior to perineal Arctic sea ice soon becoming seasonal.

Shrinking of winter, one year at the time

~The bitter cold "Arctic Blast" isn't as big as it use to be

~Visual proof of Global warming very apparent,  especially when La-Nina periods look like El-Nino

          Winter 2021-22 started small:

In fact millions of square kilometers smaller than 1977,  2016 very powerful El-Nino warming is comparable to modest La-Ninas during  2020 and 2021 as well,  astounding if you think of it.  The only quadrant from North Pole apparently not so much changed since 77 is the Russian side.  Temperatures at 600 mb are more influenced by greenhouse gases and surface temperatures than the stratosphere,  which tends to cool when the troposphere warms.  600 mb is also the closest pressure level to the density weighted temperature (DWT)  of the entire troposphere.  

Latest December mean 600 mb winter temperatures have equally shrunken in extent quite visibly.  In particular in the Canadian Arctic, North Pacific and Atlantic.  2021-22 loss of the Canadian Arctic frost continental wide 'bite" was particularly felt on the Eastern North American coast.  Notably because the extent of cold Polar vortex centers,  highly circulating influential vortices,  are smaller.  It does not mean that smaller vortices are warmer,  they can be just as cold as ever or even more deeply cold.   Cold Temperature North Poles of smaller extent are equally mobile and can navigate the Globe rapidly,  easily making people forget the warm winter they enjoyed so far.  Again it is quite obvious that the new world climate winter order will be dominated by Siberia.  Implying dramatic changes not experienced by humans in many parts of the world.  In particular NW Europe,  the Canadian Archipelago CTNP vortice has huge implications if absent.  Namely the Gulf Stream cyclones can turn Westwards instead of Northeastwards towards Ireland and the UK.  Alaska benefited extreme warming for lack of the Canadian Archipelago bulge as well.  The other large unknown is what will this do to the Gulf Stream itself,  in the long run a significant Atmospheric circulation change also gets to influence Ocean currents.  WD Jan12 2021
