Arctic sea ice “death spiral” marches on

Here is the updated Arctic sea ice volume graph as calculated by the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) at the Polar Science Center:

I think it’s pretty safe to say that we’re going to have a new record volume low, although the difference with 2010 and 2011 has become smaller. Right now it’s 1249 and 730 km3 respectively.

Here is Wipneus‘ version with the calculated “expected” 2012 values (dotted lines), based on the same date values of 1979-2011 and an exponential trend.
A caveat from Wipneus: “Note that the statistical error bars are quite large.”
