Arctic warming feedback

In 2012 Arctic Sea Ice was only half of the 1979-2000 average.
The decline is accelerating, because the additional water surface absorbs more warmth then the ice.
Because a third of the Arctic Ocean is shallow, the icy underground will melt, releasing large quantities of methane. Methane is greenhouse gas with a much greater greenhouse warming effect than C02, taking the arctic warming into third gear.
