As much as I hate to say it, Gov Perry is 100% correct.

Perry raised his voice and said: “To stand up and say that 100 percent of global warming is because of human activity, I think on its face, is just indefensible.”

The climate has been on a warming trend for hundreds of years — this continues today. The debate as to how much of the current warming is natural and how much is due to human activity is very active.
