Annual Downtrend of Arctic Ice Continues

Arctic Sea Ice Reaches Second Lowest Minimum in Satellite Record,
NSIDC, September 23, 2019.

MAIN POINTS

Tied-Second Lowest
"On September 18, Arctic sea ice reached its likely minimum extent for 2019. The minimum ice extent was effectively tied for second lowest in the satellite record, along with 2007 and 2016..."

Previous Lows
"This year’s minimum extent was effectively tied with 2007 and 2016 for second lowest, only behind 2012, which is the record minimum."

Reinforcing Downward Trend
"...reinforcing the long-term downward trend in Arctic ice extent. Sea ice extent will now begin its seasonal increase through autumn and winter."

The Trend
"The 13 lowest extents in the satellite era have all occurred in the last 13 years."

Lower Yet?
"...a shift in wind patterns or a period of late season melt could still push the ice extent lower."

Consequences

The annual cycle of Arctic cooling and warming is a key regulator of Northern Hemisphere climate & weather. It has already changed significantly, and is now changing rapidly.

Broken Cycles
These Arctic changes have disrupted the seasonal cycles of the traditional relationship between the Tropics and the Arctic, changing the patterns of the timing, the amounts, and paths of the movements of the vast amounts of Tropical moisture and heat to the Arctic, as the planet strives to balance the imbalance of our annual seasonal cycle. It looks to me like the shape of the atmosphere itself has changed in response to holding more heat, with the Equatorial Bulge expanding further North and South, altering its angle of decline down to a very weakened, slowed, and expanded mid-Winter Vortex.

Dawn of a New Age
This warming and expansion of the Tropics, when coupled with the warming and weakening of the Polar Vortex, has already radically changed the character and timing of our seasons out of their traditional ranges, and these ongoing changes are in the process of rapidly establishing whole new sets of seasonal seasonal weather patterns, changes that are still being driven forward at an alarming rate, around the whole Northern Hemisphere.

So Far
What we have seen so far are merely the first of the significant changes that are just beginning to disrupt every aspect of climate and our interrelated ecology. Right now we are experiencing events signaling the beginning of the final loss of our traditional climate as this new, warmer age on Earth fully and finally establishes itself. These changes entail sweeping away all human and natural systems dependent on the old, cooler climate, and replacing them with human and ecological systems better equipped to deal with this new, hotter climate.

Less & Less
The new configuration of climate we are building is going to entail a lot less humans living in a much less fertile and productive ecology.
