Baby it's cold outside - Global warming in winter
Like clockwork, climate "denialists" claim that winter weather is proof that climate change is a hoax manufactured by disciples of Al Gore. To be fair, the past couple of winters hasn't been "average" in many parts of North America and Europe. But that's the point.
The latest video from Greenman3610 (Peter Sinclair) explains how declining Arctic sea ice pushes frigid air from the North out of the Arctic, drawing warmer air toward the northern seas. It may be unusually cold where you are, but look to the poles and it is a different story. Extreme winter weather may not be considered so extreme anymore.
