Sorry, her comments on supporting Paul are too far out there for me. No forgiving the shrill shill on my part. Newt taught geography and history. He has studied both for years.
It is a fact that the earths climate has changed over eons...it always will. I am not blaming man for it but even I know history shows changes in land, continents and species.
Keep in mind that Gingrich has been asked about this repeatedly for a decade now. His position has always been that "We don't know what is causing it."
Personally, I don't know what to think. I believe that there are some problems with how scientists are currently measuring the planet's temperature versus even 50 years ago. If they say that CO2 levels are going up, based on ice core samples, I can accept that with the caution that we know that research HAS been falsified for political agendas. And we also know that any increase in CO2 should be taken care of by increase green plant activity. And we don't really know that the types of increases people are talking about have any real effect on global temperatures.
In short, I'm with Newt on this one: Ignoring scientific research jest because we don't agree with the researchers politically is stupid. There may or may not be something going on, but we need to know a lot more.
