We haven’t spent much time looking at Arctic Sea Ice this year, partly because I’ve rather lost interest in it as any sort of climatic indicator. This year’s melt seems similar to 2011 according to the comparison graph provided by Japan’s National Institute of Polar Research.
The DMI graph also seems to indicate that melt has turned the corner, but shows the 2015 data higher than 2011 unlike the graph above:
Arctic air temperature from 80°N is well below the freezing point of seawater now:
Of course, since sea ice is highly prone to the vagaries of wind and weather, it could still take a turn downward in the next few days before starting back up again.
One of the things that I have come to notice about Arctic sea ice is that it appears to have reached a new plateau or regime, note how since 2007 the data seems to oscillate about the -1 million square kilometer line:
My personal opinion is that this new quasi-stable regime is related to increased surface soot and changes in the AMO (Atlantic Multidecadal Oscillation). Since the mid-1990s we have been in a warm phase, Now the AMO is now turning sharply negative, and next year might be quite different than the past eight.

12-month running avg AMO continues to drop. August ’15 value (-0.9 SD) lowest since ’94. Cold NAtl persists.
Only time will tell if this change in the AMO will change the future of Arctic sea ice.
