A survey on the 1372 leading scientists in the field of climate-science revealed that more than 97% of them support the conclusion of the Intergovernmental Panel on Climate Change that global-warming is
* real
* man-made
* a danger

Oh, and one more:
Quote: "the relative climate expertise and scientific prominence of the researchers unconvinced of ACC (anthropogenic climate change) are substantially below that of the convinced researchers."





If 97% of car-mechanics told you that your car is an accident-waiting-to-happen and needs repair ASAP, would you call the debate "still open"?

Everyone knows that scientists base their conclusions on facts and facts have no place in Republican politics.
