A warming event in the arctic might have affected the polar vortex but it’s a leap of faith to believe the warming event in the polar region was due to man made global warming.I'm 79 years old but I don't see the relevance of age...as the point I was making was much colder temperatures is according to climate change evangelistas, ....climate change is the cause...
The increase could be tied to human caused climate change.
What has been proven is that a warming event destabilized the polar vortex above the North Pole dislodging the arctic air mass to the Deep South.
