Climate science seems to work on the principle of “let’s find an explanation which kinda sorta makes sense if you don’t think about it, and then blame (whatever it is) on CO2.”
A classic example is Hansen’s claim about the current cold in Europe.
Back to the cold air in Europe: is it possible that reduced Arctic sea ice is affecting weather patterns? Because Hudson Bay (and Baffin Bay, west of Greenland) are at significantly lower latitudes than most of the Arctic Ocean, global warming may cause them to remain ice free into early winter after the Arctic Ocean has become frozen insulating the atmosphere from the ocean. The fixed location of the Hudson-Baffin heat source could plausibly affect weather patterns, in a deterministic way — Europe being half a Rossby wavelength downstream, thus producing a cold European anomaly in the trans-Atlantic seesaw.

His explanation doesn’t work. Last winter showed the same weather pattern – yet sea ice extent was the highest in years – and had the latest peak on record.
