The wacky jet stream and how it affects the polar vortex

[Champion Jack]

The polar vortex, normally tucked away much closer to the Arctic, has swept down several times this winter, bringing cold temperatures and snow to large segments of the U.S. east of the Rockies. Many experience this and either forget or doubt what the data show: that 2013 was the fourth-hottest year on record (or second-hottest without an El Niño), that greenhouse gas emissions are causing the atmosphere to trap more heat, that climate change is a problem.

and that the jetstream had pulled the normal polar vortex, which is there anyway, out of shape.
