In recent years, October has seen some rapid recoveries of Arctic ice extents.  But this year may become something special.

With the early onset of Siberian snow cover and the resulting surface cooling, ice is roaring back, especially on the Asian side. Consider the refreezing during the last 11 days through yesterday.

The graph compares extents over the last 10 days.

2017 has reached 5.7M km2, 460k km2 more than the strong 2016 recovery, now tracking the 10 year average.  2007 remains 1.1M km2 behind, and 2012 is 1.7M km2 less than 2017.  SII is showing similar ice gains in October.
