Isn't there a case to be made that colder winter weather in the Northern Hemisphere is a feature of climate change, produced by changes in atmospheric and oceanographic currents caused by warmer summertimes? I never heard the term "Polar vortex" before global warming became a thing.
Yes, when the temperature differential between the poles and the equator is reduced (the poles are warming faster), the jet stream tends to wobble and polar air can drift south over us.
Here in the UK, we get warm weather when the jet stream is north of us, cold weather when it is south, and changeable when it is overhead.
Polar vortex is a relatively new term to me too, as is the cold blob.
