JAXA ARCTIC SEA ICE EXTENT :- 4,390,697 km2(August 24, 2019)
JAXA daily extent loss in the last week quite a bit below average and even more so on this day.
- Extent is still 2nd lowest in the satellite record (49 days at lowest this year),
- Extent is 571 k greater than 2012, 359 k less than 2016.
- Extent loss on this day 22 k, 32 k less than the average loss on this day of 54 k.
- Extent loss from maximum 9,880 k, 580 k (6.1%) greater than the average of 9,310 k loss from maximum by this day,
- Extent loss from maximum to date is also second highest in at least the last 12 years, only second to 2012,
- On average 94.2% of the melting season done, with 20 days to average date of minimum (13 September).
The Perils of Projections.
Average remaining melt (0.57 million km) would give a minimum of 3.82 million km2, 2nd lowest in the satellite record, 0.64 million km2 above the 2012 low of 3.18 million km2 and 0.20 million below the 2nd lowest in 2016 of 4.02 million km2.
Ice Melt Outlook The peak days of daily melt are past. From now to minimum, on average daily extent loss will gradually but erratically reduce until the minimum.
On average, each day now consumes 5% of the time available for further extent loss. So far weather events seem to be favourable to slow ice extent loss. If, as in 2017 & 2018, extent loss from now was very low, the final minimum could be in excess of 4 million km2 in 4th place.
