"The number of studies that have proven no human link to Global Warming--None."

Franken either is or plays scientifically illiterate here. A study has an incredibly hard time proving an absolute negative--that there is NO correlation between X and Y. I haven't gone over the global warming debate for a few years, but, AFAIK, the state of play is that a large majority of scientists overall believe that man-made global warming is real. A much smaller majority, but still a majority, of climate scientists believe it. The rest believe that the computer models are only as good as the assumptions, and that there are natural cycles that overwhelm any human-generated effect.
