Arctic sea ice in phase space

Another September has passed, and with it the annual minimum extent of Arctic sea ice. This year we saw a minimum of 5.1 million sq km, which is quite a bit more than the minimum of last year.

As noted before, there is a distinct break just after 1995.

I still haven't seen anything that would lead me to reject the possibility that we are tracing out a new area of stability (hashed circle). The lag means that the state in 2014 will lie along the lower blue line (exact position will depend on next year's area) and in 2015 will lie along the higher blue line.
