JAXA GLOBAL SEA ICE EXTENT: 22,897,229 KM2 as at 25-Sep-2020
- Extent gain on this day 162k, 121 k more than the average gain on this day (of the last 10 years) of 41k,
- Extent gain from minimum on this date is 6.18 million km2, 0.53 million km2, 8.0% less than the 10 year average gain of 6.71 million km2.
- Extent is at position #8 in the satellite record
- 2020 Extent is 0.34 million km2 MORE than 2019,
On average 74.0% of sea ice gain from minimum to maximum done, and 40 days to maximum
Projections of the Unknown Quantity. (Table JAXA-AA1)
Average remaining sea ice gain (of the last 10 years) would produce a maximum in November 2020 of 25.26 million km2, 1.50 million km2 above the 2016 record low maximum of 23.76 million km2.
___________________________________________________
The false maximum was reached on the 28th June. We are at the end of extent losses up to the false minimum of early September. We are now in the late run of extent gains to the “maximum maximum” for the year in late October/early November.
N.B. In 2016 the maximum was reached on the 7th July. i.e. the November maximum was less than the “false” maximum.

___________________________________________________
Both Arctic and Antarctic daily extent gains much higher than average on this day, resulting in an extreme global sea ice extent gain to add to above average increases in the 3 days before.
As a result Global sea ice extent now 8th lowest in the sateliite record from 4th lowest on the 21st September. .
