AP article: Former astronaut speaks out on global warming - BostonHerald.com

SANTA FE, N.M. - Former astronaut Harrison Schmitt, who walked on the moon and once served New Mexico in the U.S. Senate, doesn’t believe that humans are causing global warming.

"I don’t think the human effect is significant compared to the natural effect," said Schmitt, who is among 70 skeptics scheduled to speak next month at the International Conference on Climate Change in New York.

Dan Williams, publisher with the Chicago-based Heartland Institute, which is hosting the climate change conference, said he invited Schmitt after reading about his resignation from The Planetary Society, a nonprofit dedicated to space exploration.

Schmitt resigned after the group blamed global warming on human activity. In his resignation letter, the 74-year-old geologist argued that the "global warming scare is being used as a political tool to increase government control over American lives, incomes and decision making."
