There was very little loss of multi-year ice during the summer of 2013. The graph below shows the survival rates for sea ice in the Arctic Basin, grouped by age.
But it gets much worse for alarmists. Almost all of the thick ice is located far away from the Fram Strait, where it will survive the winter, and be a metre thicker next spring. Another winter/summer like 2013, and the death spiral with be officially dead.
The area of 4+ ice will nearly double over the winter, and the volume will increase by even more.
I predict that if the Arctic sea ice extent and volume increases between now and 6 years time, then there will be no AR6. 😉
The direction the ice is moving at the moment will shift a lot of it out of the Arctic circle.

I see some very thick 3 to 5 year ice to the north of Greenland, already moving very slow in the dark blue scale; likely the ice continues to thicken and slow throughout the fall and winter.
