Worldwide Weather Patterns are already going Nuts. Baseball- sized hail, daily- weekly Tornadoes, where there hasn't been recorded before, Flash Floods...
I guess that's a better Indicator for the real State of Arctic Ice than PIOMAS (still, very, very bad- if not catastrophic), Extent (holding on, but that's no good Sign, either).
Based on what's already happening weather- wise and of course the Nuclear Standoff off the Coast of NK, I don't have any optimism at all, for this Summer.
