The Arctic sea ice extent has been a roller coaster this year.
Normally it's pretty predictable - the ice begins to melt during the spring months, accelerates during the summer, slows toward the end of summer, begins recovering around October, then steadily increases in extent from November thru January.
This year there was a rapid acceleration in the melt during the summer. At first it seemed as though the ice extent wouldn't decrease as much as in 2007, but after a big acceleration almost got there (and did break the record in terms of volume). Then there was a fairly rapid recovery in October, and some of the deniers were predicting Arctic ice extent would return to 1979-2000 average levels (some even predicting it would recover to 1979 levels).
Well, as I predicted, Arctic sea ice didn't even come close to recovering to that level. Not only that, but suddenly the recovery has essentially ceased, and suddenly the extent is below the 2007 record low.
Granted it's only maybe 2 weeks of flatlining, but it's extremely strange to see the Arctic sea ice recovery stop in December, of all months.
Anyone have any ideas what's going on?
