Loss of heat by radiation from the ocean is much lower than previously thought, which could account for the more rapid than expected warming in the Arctic.
Far infrared emissivity of the ocean previously unavailable has been measured to be substantially lower than originally assumed, which is important even during the winter when the sun isn't shining.

It's a vicious cycle! More thawing of ocean ice means more trapped heat in non-frozen water surfaces which leads to more thawing and, thus, more non-frozen areas of water to trap more heat.

Thanks Joe,

Interesting information about the effect of low vs high clouds in the second link to phys.org. The first links to pnas.org is the original research publication on IR emissivity.

This article mentions a bit about the sea ice and record temperatures:

Here's what the White House says:

and this one shows how Congress feels about it:
