[font size=3]KENOSHA, Wis. (AP) The planet has faced climate change forever and humans' pollution might not be to blame, Republican U.S. Rep. Paul Ryan said Monday during a debate against his Democratic challenger.
Ryan, favored to win re-election to his seat representing GOP-leaning southern Wisconsin, faced off against businessman Rob Zerban for an hourlong forum that touched on world events, domestic politics and the economy. One of the sharpest differences came when the moderator asked each candidate if he thought human activity is to blame for changes to the planet's climate.
"I don't know the answer to that question," Ryan said. "I don't think science does, either."
Ryan also said efforts to combat climate change are costly and unproven, a popular position among the Republican base he will need should he seek the GOP's presidential nomination in 2016.
