Thin ice

More analysis of this years Arctic ice shows that it's now 90% one-year ice, only 10% 2+ year ice.  One-year ice is pretty thin compared to multi-year ice, and melts and breaks up more easily.  It's not a happy omen.  (Source: BBC)

Edit:

This from the CC with Walt Meier NISDC and Ron Kwok NASA/JPL last Monday:

Current multiyear ice is 9.8%
That is a record low since 1981
That is 66% lower that the 1981-2000 average
