Added to this is new research out of the University of Washington which suggests that even if the planet warmed enough to melt all polar sea ice, it could still recover if the temperatures cooled again.

“Lots of people think of the Arctic as just a flat expanse of white. This couldn’t be further from the truth. There are all sorts of cracks (leads) and mountains (ridges), similar to tectonic plates.
