This is one of the clearest examples of a regime shift in the recent historical record. I think we still need to be open to the possibility that natural variability has played a role in the recent warming of the Arctic, but with each year that goes by without a return to the pre-2007 summertime Arctic climatology it seems more likely that the remarkable change that we have witnessed will prove to be irreversible.
