I saw this. Three questions come to mind. 1) what did this look like going back some 2-3000 years? Of course we don't know, so we cannot compare and make a claim as to what this trend means against past trends. 2) What caused the sudden spike down? And what caused the sudden recovery? 3) what's going to happen next?
So if you saw it, why didn't you report it?
Snot-nosed cherry picker.
The sudden spike down was caused by extended temperature anomolies reaching 10 or 20C at maximum for a long period of time in a statistically significant (in terms of changing climate versus changing weather) manner. This is orders of magnitude more serious (and more localized) than any of the global warming models predict, and has been one of the reasons people are claiming such different things.
A solid possibility on the recovery spike - Pack ice which is breaking up doesn't just melt into water immediately. It spreads out into small, floating chunks of surface ice which get counted as "low ice coverage." If a lot of this happens in a warm summer, the following winter you could be faced with a huge, several-inches-thick pack of ice, instead of a smaller, dozens-of-feet-thick pack of ice - particularly if the surface water is much fresher than the ocean water (and easier to freeze).
