Many Republicans doubt that man-made emissions of greenhouse gases are responsible for global warming. And you can count presidential candidate Tim Pawlenty as one of them, The Miami Herald
The former Minnesota governor doesn’t dispute the fact that temperatures are rising. But, “The more interesting question is how much is a result of natural causes and how much, if any, is attributable to human behavior. And that’s what the scientific dispute is about,” Pawlenty says.
So what’s his take? “It’s something we have to look to the science on. The weight of the evidence is that most of it, maybe all of it, is because of natural causes. But to the extent there is some element of human behavior causing some of it — that’s what the scientific debate is about.”
