Mitt Romney's views on global warming are back in the news. This week, he reaffirmed his skepticism about humans contributing to climate change. CBS News detects a "rightward shift" as the campaign goes on, and both Democrats and Rick Perry agree, notes CNN. Judge for yourself, as Politico rounds up some of his statements on the subject:
- Thursday: "My view is that we don’t know what’s causing climate change on this planet. And the idea of spending trillions and trillions of dollars to try to reduce CO2 emissions is not the right course for us."
- August: "Do I think the world's getting hotter? Yeah, I don't know that, but I think that it is. I don't know if it's mostly caused by humans."
