From JAXA Sea Ice Extent Data - a bit more

Another month gone by - on average now only about 45 days left to minimum with ever-reducing daily sea ice loss.

The July '22 monthly average is 7.93 million km2, 12th lowest in the 44 year satellite record. This is 0.62 million km2 above the long-term linear trend, 0.54 million km2 above July '21 which was 3rd lowest in the satellite record.

The 365 day trailing average continues to rise, as it has since April '21. This is simply because 2021 extent was higher than 2020, and 2022 daily extent is mostly higher than 2021.

The July 2022 bilan of Arctic Sea Ice Area "relative area wise". July is the strongest melting month. So let's find out in which sea the highest portion melted.
The laggards are
BEAU   - 9%
CAB     - 9%
relatively slow melting in
ESS    -30%
CAA    -33%
CHUK  -35%
medium melt rate in
GRØ    -43%
higher melt rate in
LAP     -59%
The leaders are
BAF     -78%
KAR     -79%
HUD    -88%

Okhotsk, St Lawrence, Bering and Barents not evaluated, they have melted completely.

I added the monthly extent value for July 2022 into my long-term plot where I calculate the extent anomalies from 1979 up to now.
The average (1979-2022) July extent is now 9.08 M km². July 2022 had an average extent of 8.25 M km², which is 0.83 M km² less than that long-term average.
This month's value was again above the long-term linear trend line (very unusual for a July!). The difference of the actual month from that trend line is +0.40 M km² (calculated from the linear trend line this July should have been at 7.85 M km²).
The slope of the long-term linear trend line has not changed (-0.0536).

JAXA sea ice extent - a bit more

The plume of sea ice extent projections still show a fair range - with the vaerge pretty much on 4.75 million km2.

The graph of this melting season's daily sea ice change shows fairly clearly the lack of any major melting events.

The 365 day trailing average sea ice extent shows a continuous increase this year - simply because 2022 extent is consistently above that of 20211. If daily sea ice change continues at the 10 year average it will continue to increase
