If this keeps up until the minimum, the 2014 melting season will have been excellent for restoring some of the ice lost since the first big volume drop in 2007.
And it has kept up. The difference with the post-2010 years and 2007 has increased a little bit more, and sea ice volume levels according to PIOMAS are effectively at the same level they were in 2009. In short, an astounding rebound. It was always clear that the Arctic could be very volatile, but this swing is huge and shows what two consecutive melting seasons with conditions that are relatively good for ice retention (2013 was cold and cloudy, 2014 cold and cloudy at the start, followed by little movement) can mean for the ice pack.
The PIOMAS sea ice volume graph produced by Wipneus shows the uptick and relative position of the 2014 trend line even more clearly:
