Arctic Sea Ice Death Spiral Reversed (Yet Again)

In the Daily Mail, David Rose quotes the always reliable Judith Curry saying "the Arctic sea ice spiral of death seems to have reversed."

By my count, there's been 7 reversals of the death spiral since 1979, including the famous reversal of the mid-90s and the huge reversal in 2008. So many reversals that Arctic sea ice extent has spiraled up by average of -44,000 square kilometers a year since 1979.

That's some fancy spiraling. Any more spiraling like this and we're going to have a great abundance of negative ice in a few more decades. Where will we put it all?
