In the race for the GOP presidential nomination, even candidates who previously accepted climate science and backed cap-and-trade are backtracking and changing position as fast as they can.

"The American public is less likely to believe in global warming than it was just five years ago. Yet, paradoxically, scientists are more confident than ever that climate change is real and caused largely by human activities."

"Pipeline operators and their trade organizations shaped, managed and provided sizable funding for numerous safety studies conducted by the federal agency that regulates the industry, a Chronicle investigation shows."

"The sun is heading into an unusual and extended hibernation, scientists predict. Around 2020, sunspots may disappear for years, maybe decades. But scientists say it is nothing to worry about. Solar storm activity has little to do with life-giving light and warmth from the sun."

"Sometimes it seems hard to believe how much skepticism still exists about climate change, with the scientific community in near-unanimous agreement that yes, it's happening and yes, it's our fault. But as Minnesota State Senator Michael Jungbauer reminded us yesterday, most of that dissent comes from people who are more or less clueless about the science."

"Judging from an annual survey by researchers at Yale and George Mason universities, the American public is roughly as fractured in its attitudes toward climate change today as it was last year."
