JAXA ARCTIC SEA ICE EXTENT:  9,304,459 KM2 as at 22-Nov-2020

- Extent gain on this day 183k, 97 k more than the average gain on this day (of the last 10 years) of 86k,
- Extent gain from minimum on this date is 5,750 k, which is 396 k, 7% more than the 10 year average of 5,353 k.

- Extent is at position #2 in the satellite record

- Extent is  273 k LESS than 2019,
- Extent is  594 k MORE than 2016,
- Extent is  362 k LESS than 2012
- Extent is  686 k LESS than 2007
- Extent is  404 k LESS than the 2010's Average
_____________________________________________
On average 54.3% of extent gains  from minimum to maximum done, and 109 days to maximum

Projections. (Table JAXA-Arc1)

Average remaining extent gain (of the last 10 years) would produce a maximum in March 2021 of 13.82 million km2, 0.06 million km2 below the March 2017 record low maximum of 13.88 million km2.

Which is the best answer to Sep-2012 ASI lost (compared to 1979-2000)?
50% [NSIDC Extent] or
73% [PIOMAS Volume]

Volume is harder to measure than extent, but 3-dimensional space is real, 2D's hide ~50% thickness gone.
-> IPCC/NSIDC trends [based on extent] underestimate the real speed of ASI lost.

- Extent gain on this day 36k, 33 k less than the average gain on this day (of the last 10 years) of 69k,
- Extent gain from minimum on this date is 6,033 k, which is 408 k, 7% more than the 10 year average of 5,626 k.

- Extent is at position #2 in the satellite record

- Extent is  170 k LESS than 2019,
- Extent is  499 k MORE than 2016,
- Extent is  403 k LESS than 2012
- Extent is  480 k LESS than 2007
- Extent is  378 k LESS than the 2010's Average
_____________________________________________
On average 56.9% of extent gains  from minimum to maximum done, and 106 days to maximum

Projections. (Table JAXA-Arc1)

Average remaining extent gain (of the last 10 years) would produce a maximum in March 2021 of 13.84 million km2, 0.04 million km2 below the March 2017 record low maximum of 13.88 million km2.
