Quote from skysidhe: "That said did you know the polar ice cap once covered most the upper part of the US? I mean the earth has been warming up for sometime. Perhaps these warming and cooling trends are natural phenomenon. I am sure our pollution contributes but would it be happening anyway?"
That is so obvious, yet no one seems to want to mention it. It's seemed logical to me, long before the politicization of global warming, and even before the global cooling fad of the 70s
