Echoing a report from some German scientists, Joe Romm says "Historic Low Arctic Ice is a “Consequence of Man-Made Global Warming with Global Consequences”
But if we look up the original German report we see in their figure 3 that there is a large area that has GAINED ice as well as a fringe that has lost ice. The legend on the figure says: "Differences of ice concentrations of the minima in 2007 and 2011. Green: ice covered in 2011, not in 2007, red vice versa" So the tale is more complicated than it sounds. It is clearly regional fluctuations that are happening rather than some overall change.
But when were the "minima" recorded? The Germans do not say but Romm's comment was on 12th Sept. so it was presumably some time before that. Steve Goddard, on the other hand, has an updated version of their graph which IS dated. See below. Clearly the ice area that has increased is greater than the area that has been lost. The overall ice cover is GREATER in 2011 than in 2007
Dark green is September 26 ice present in 2011 that wasn’t present on the same date in 2007. Red is the opposite. Romm calls this a record low.
