WASHINGTON (AP) — Remember the polar vortex, the huge mass of Arctic air that can plunge much of the U.S. into the deep freeze? You might have to get used to it.

A new study says that as the world gets warmer, parts of North America, Europe and Asia could see more frequent and stronger visits of that cold air. Researchers say that's because of shrinking ice in the seas off Russia.

Normally, the polar vortex is penned in the Arctic. But at times it escapes and wanders south, bringing with it a bit of Arctic super chill.

That can happen for several reasons, and the new study suggests that one of them occurs when ice in northern seas shrinks, leaving more water uncovered.

Normally, sea ice keeps heat energy from escaping the ocean and entering the atmosphere. When there's less ice, more energy gets into the atmosphere and weakens the jet stream, the high-altitude river of air that usually keeps Arctic air from wandering south, said study co-author Jin-Ho Yoon of the Pacific Northwest National Laboratory in Richland, Wash. So the cold air escapes instead.

From Here.

Yep Len. Pandora's box is well and truly open now. There is still time to push it closed but the will is not there.

Of course not! the present capitalist-ccentric society we have sees no profit margins in financially speaking, forgetting that extinction does not care how full your bank account is or not.

I have been living under the US vortex this past winter/summer, june and july were like october-november more than summer.
