Almost Fall

The Autumn Equinox happens at 5:04 AM this Friday, September 23rd.   Snow covers a good chunk of the Canadian Arctic Archipeligo.  The Arctic sea ice reached its minimum a week ago, second lowest in the satellite era (but not lowest in paleoclimatological record, discussed here) despite the very late start of the Eastern Canadian/Western Greenland freeze season due to a prolonged period of a strong negative AO atmospheric circulation (discussed here) which undoubtedly affected the melt season.
