Mid June Arctic Ice Returns to Mean

The Arctic ice melting season was delayed this year as shown by the end of May (day 151) surplus of 600k km2 over the 16-yr average.  Since then both MASIE and SII show a steep decline in Arctic ice extents, now matching the average for June 15 (day 166).  The reports show that Barents alone lost 320k km2, Laptev down 200k km2, Baffin Bay lost 165k km2, Chukchi, Kara, Greenland seas all lost around 100k km2 each.

For the month of June Hudson Bay will take the stage.  Above average early in June. Hudson Bay lost 100k km2 the last six days. Being a shallow basin, it will likely lose much of its 1M km2 in a few weeks.

Why is this important?  All the claims of global climate emergency depend on dangerously higher temperatures, lower sea ice, and rising sea levels.  The lack of additional warming is documented in a post Adios, Global Warming

The lack of acceleration in sea levels along coastlines has been discussed also.  See USCS Warnings of Coastal Floodings

Also, a longer term perspective is informative:

The main deficits are in Laptev and Barents Seas, mostly offset by surpluses in Beaufort, Baffin and Canadian Archipelago.
