One of the consequences of the warming planet; and in particular of polar amplification (exceptional warming in the Arctic) is a weaker jet stream. This in turn makes it more likely for the jet stream to have large loops, which can spill cold air down one region while have warmer regions right next to it. The USA is particularly susceptible to this; California can get the heat while Eastern USA gets Arctic air and blizzards.
This is a completely serious consideration; with a good evidential basis. A good reference for this association is here:
- Evidence linking Arctic amplification to extreme weather in mid-latitudes, Geophysical Research Letters Vol 39, Iss 6, 28 March 2012, by J. A. Francis1 and S. J. Vavrus
You should be able to find more about this association of warming with localized extreme winters very easily if you look. It is thoroughly serious and although it sounds absurd at first sight it is perfectly sensible.
