The return of JAXA confirms the NSIDC data trend, except in that the NSIDC daily extent losses for the 2nd and 3rd July were even higher.
JAXA ARCTIC SEA ICE EXTENT: 8,466,628 KM2 as at 04-Jul-2021
- Extent loss on this day 151k, 63 k more than the average loss on this day (of the last 10 years) of 88k,
- Extent loss from maximum on this date is 5,771 k, which is 337 k, 6.2% more than the 10 year average of 5,433 k.
- Extent is at position #1 in the satellite record
- Extent is 40 k LESS than 2020,
- Extent is 135 k LESS than 2019,
- Extent is 132 k LESS than 2016
- Extent is 208 k LESS than 2012
- Extent is 331 k LESS than the 2010's Average

On average 54.2% of extent losses from maximum to minimum done, and 72 days to minimum
Projections. (Table JAXA-Arc1)
Average remaining extent loss (of the last 10 years) would produce a minimum in September 2021 of 3.87 million km2, 0.69 million km2 above the Sept 2012 record low minimum of 3.18 million km2, and 3th lowest in the satellite record
To equal the 2020 minimum of 3.55 million km2 requires further melting of 4.91 million km2, 6.8% above the 10 year average remaining melt.
To equal the linear trend 2021 minimum of 3.93 million KM2 requires further melting of +4.54 million KM2, -1.4% less than the 10 year average remaining melt.

The return of JAXA confirms the NSIDC data trend, except in that the NSIDC daily extent losses for the 2nd and 3rd July were even higher. I am surprised at the size of these losses, given the weather conditions of late in the Arctic.
This is the first time this year that the simple projection results in a minimum of less than the linear trend value for the 2021 minimum.
