JAXA ARCTIC EXTENT :- 12,563,633 km2(April 27, 2019)
- Extent is 2nd lowest in the satellite record, 65k greater than 2016.
- Extent loss on this day 45k, 0 k more than the average loss of 45 k on this day.
- Extent loss from maximum 1,707k, 450 k (36%) greater than the average of 1,257k loss from maximum by this day,
- On average 12.7% of the melting season done, with 139 days to average date of minimum (13 September)
The Perils of Projections.
Average remaining melt would give a minimum of 3.94 million km2, 2nd lowest in the satellite record, and 0.76 million km2 above the 2012 low of 3.18 million km2.
On 22nd April, 2016 started its 2 months as the front runner with steep declines in extent. To become lowest again, 2019 will have to match or exceed the above average extent losses of 2016 from now until at least June.
Other Stuff
GFS indicates that overall the Arctic temperature anomaly will increase from around +2 to well over +4 degrees over the next week to 10 days. The strongest and most persistent +ve anomalies will be in a broad band over the Pacific half of the CAB, the CAA, Baffin Bay and Greenland. The Okhotsk and Bering Seas should be warm enough to completely melt out over the next week to 10 days.
