From this post:

Satellite images are showing that the cold spell is helping the sea ice expand in coverage by about 2 million square kilometres, compared to the average winter coverage in the previous three years.

I'm starting to think that the left only pays attention to the Arctic in the summer--when it's supposed to melt.

At the "National Snow and Ice Data Center", check out the massive, breathless coverage of the summer melting season here and here. Then see how much coverage you can find about the winter freezing season.
