There's obviously still a lot of heat in the system, but we're only at the start of the freezing season. It'll be interesting to see if this slow start impacts on the maximum extent and volume numbers.
There's never a dull moment in the Arctic.
I think its all about volume recovery and momentum.
Every day with reduced extent is a day where the ice in place loses an opportunity to add few CM of thickness over all.
It means ice not in place loses time available to de-salinate and harden.
In effect, each faction of extent which fails to expand will translate into a fractional reduction in eventual volume - 1/10th of a percent? 1/20th? - which while not significant on its own, like interest on debt, will accumulate far rapidly than we would like.
So, while the most visible metrics - extent and area - are changing pretty dramatically, what we can't see are changes in the quality of the ice and dynamics of heat exchange which I think are really bad, and may express themselves very dramatically next season.
Hope for a return of the Polar vortex!
