What caused the volume loss in PIOMAS?

Behind all of my blogging on sea ice is the volume loss, which is driving the changes. The volume loss is shown by other data (e.g. Submarine upward looking sonar, ICESat, IceBridge, Cryosat 2), but the most detailed picture is that provided by PIOMAS. What is driving the volume loss in PIOMAS and is this process at work in reality?

PIOMAS Gridded Data: February 2014.

PIOMAS gridded data has been released for February giving some more detail about current ice state. The peak volume for the whole Arctic is in April, thickening continues in the central Arctic into May, so there is still time for thickening but I don't expect the volume to reach the high level compared to last year. The 2013 volume pulse seems to be largely spent.

PIOMAS February 2014

In terms of PIOMAS total volume the winter sea ice seems to have lost the 2013 volume gain. What might this mean for 2014's impending melt season?

UK Floods In Context

I am tempted to make some cutting comment about those who indulge in games of 'look squirrel' and those who publicise them, but such people bore me.

There are times when only a simple graph is needed.
