People don't realize that this year's Vortex was caused by a huge former typhoon that headed with abnormal strength North to the Bering Sea, strengthening the huge high pressure system and the cold air associated with it allowing it dip much further South than normal.
I'm hearing from the warmniks that the strength of that typhoon is due to abnormal high sea temp's in the middle pacific. So just like last year, the abnormal cold weather in the US, like almost anything weather related is due to global warming.
So just as people forget about Finland, they also forget that the Polar vortex is really Damone and his low mileage BMW's fault.
