Note that Arctic ice recovers strongly in October going on average (2007 through 2018 inclusive) from 5M km2 to 8.6 M km2. 2019 was as much as 1.3M km2 below average mid-October, before ending the month 654k km2 down..The graph shows 2018 and 2007 matching with 2019 converging as of October 31. SII and MASIE show the same average for the month with SII about 170k km2 lower…
