We are experiencing a Maunder minimum type effect, meaning the harsh winter is caused by low solar activity, which is an external factor, nothing to do with global warming, which is an internal factor.
Since last summer it was predicted that this winter was going to be specially cold. This was timely reported by Jaime Maussan in his now famous and internationally renown program Third Millennium.

I'm not saying global warming is fact or BS, I'm just saying there are external factors to consider.
