I made another plot, now for the sector closest to the Antarctic coast, from 60S to 70S. Thus excluding the Antarctic land mass.
The trend is the same, pronounced cooling over 40 years.
And when you add the post by interstitial you start to see a more complete story of maybe why the sea ice average is barely changed over the last 40 years but warmer ocean water is attacking ice shelves and glaciers, to a considerable extent from underneath.
I wonder what a 50 to 60 South graph would look like.
meanwhile...
JAXA ANTARCTIC SEA ICE EXTENT: 18,156,720 KM2 as at 24-Oct-2020
- Extent loss on this day 1k, 63 k less than the average loss on this day (of the last 10 years) of 64k,
- Extent loss from maximum on this date is 0.70 million km2, 0.31 million km2, (30%) less than the 10 year average of 1.01 million km2.
- Extent is at position #34 in the satellite record of which 19 lower values are in the years before 2000
- Extent is 1,232 k MORE than 2016
- Extent is 658 k MORE than 2017
- Extent is 967 k MORE than 2018
- Extent is 600 k MORE than 2019
- Extent is 417 k MORE than the 1980's Average
- On average 6.3% of ice loss from maximum to minimum done, and 120 days to minimum
Projections. (Table JAXA-Ant1)Average remaining melt (of the last 10 years) would produce a minimum in Feb 2021 of 3.18 million km2, 1.03 million km2 above the 2017 record low minimum of 2.15 million km2.
