JAXA ARCTIC SEA ICE EXTENT :- 3,978,839 km2(September 18, 2019)
Extent gain this day 15k. 3 days below 4 million km2.
The melting season is supposed to be over. Maybe it is, maybe not.
On this day,
- Extent is 2nd lowest in the satellite record,
- Extent is 693 k greater than 2012, 393 k less than 2016, and 95 k less than 2007,
- Extent gain on this day 15 k, 17 k less than the average gain on this day of 32 k.
The Perils of Projections.
2018 remaining melt (0.04 million km & the only year left) would give a minimum of 3.93 million km2, 0.75 million km2 above the 2012 low of 3.18 million km2, 0.09 million km2 less than 2016, 0.14 million km2 less than 2007.

Ice Melt Outlook ??
It is supposed to be well into the beginning of extent gains.
The melting season thread reports new ice in several locations.
But......

NOTE I have replaced 2012 with 2018 in the Arc2 graph, as for the next few weeks 2018 had very low extent gains. I might add 2007, as until mid-October 2007 was also exceptional.
