ice cover declining even when weather patterns would suggest the decline should stall

Quite soon after the inception of this blog, data from the PIOMAS model became a prominent element in discussions on ice thickness and volume. Though corroborated by on-the-ground observations and satellite data, PIOMAS remained a model and so practically everyone was careful in not attaching too much importance to the numbers that showed a staggering decline in volume over the last decade.
In the past two years, however, more and more evidence has been accumulating, showing that PIOMAS has it largely right.
This year and last year we've seen total ice cover declining even when weather patterns would suggest the decline should stall. Moreover, it was recently announced that preliminary observational data from the CryoSat-2 satellite more or less confirm the PIOMAS modeled data.
And so we move on, going deeper into the matter, and discuss things like the precipitous drop in average thickness at the end of May 2010 that was repeated in 2011 and 2012:
