The Rime of the Ancient Mariner

Three weeks into June, Arctic ice is still plentiful The graph below show ice extents up to yesterday, June 23, 2017, day 174.

After a dip, 2017 is again above the decadal average, 300k km2 greater than 2007, and 500k km2 larger than 2016. SII 2017 is presently showing 400k km2 less ice than MASIE does with its higher resolution.

Barents Sea shows a surplus of 2017 sea ice extents inside the Arctic Circle. The graph below shows Barents this year compared to average and other years.

The black line is average for the last 11 years. 2007 in purple appears close to an average year. 2014 had the highest annual extent in Barents Sea, due to higher and later maximums, holding onto ice during the summer, and recovering quickly. In contrast, 2016 was the lowest annual extent, melting out early and recovering later. 2017 in blue started out way behind, but grew rapidly to reach average, and then persisted longer to exceed even 2014. It may yet beat out 2014 as the highest in the last 11 years.

What a difference a year makes.
