Global Warming doesn’t mean “no more winter”!

The Polar Vortex (aka the Arctic Oscillation) has been the subject of comments in 4RG. Follow these links to see how 4RG has tracked changes in this generator of the cold weather North American has been experiencing this year.

We listened why the balmy temperatures we were experiencing would change to frigid within twenty four hours. We gathered that the cause of this change was an invasion … Read more
