edit: since samsquanch isn't around these days, someone else is going to have to step up and make some ignorant comment about the use of "anomalies" in the graphics above.
Graph anomalies, no. I will however take issue with the idea graphs show the totality of what's happening up there.
A NASA study showed the Arctic Oscillation shifted last year. Satellite imagery clearly shows the Pacific Decadal Oscillation shifting to it's cold phase this year. These ocean oscillations happen in cycles. A recent study suggested ocean effects could explain 70% of recent warming. Some say more. There is no evidence pointing to CO2 forced warming as the smoking gun responsible for the recent arctic melt. There are however many possible natural forces which may explain it.
Ocean oscillations.
Soot blowing North from the more industrialized Northern Hemisphere.
Winds blowing large fragmented ice chunks south preventing buttressing on the larger packs.
Volcanic activity.
Cloudless skies.
High solar activity with ocean lag.
And after all that natural force stuff, perhaps even a tiny amount of greenhouse gas irregularity.
In 1942 the RCMP schooner, the St. Roche sailed the Northwest Passage twice in a single year from either direction. After that the arctic cooled. The Northwest passage refroze. Recently it warmed. This happens. Increased melt, then refreezing happens in cycles within a much longer warming trend coming out of ice ages.
Again though, here's the thing. Last year we saw a record melt. It was suggested this meant the ice had thinned to a point from which it could not recover. The suggestion was this proved an arctic warming which would continue from that point to a time when we would see an ice free arctic. This year however Mother Nature disproved that. There is more arctic ice now than there was last year at this time. Significantly more.
That's the story we should be hearing from the media. They made loud pronouncements concerning what happened last year, and what was supposed to happen this year as a result. They were wrong. We don't hear about it. Instead we see stuff like snazzy little animations showing the melt from 79 to 2007. It's a lie unless you tell the whole story.
