"Former Vice President Al Gore is going where few environmentalists -- and fellow Democrats -- have gone before: criticizing President Barack Obama's record on global warming."

"Here's one advantage to armadillos' steady northward march across the Southeast United States: They're awfully handy to have as bait if, say, you're a wildlife biologist looking to trap an alligator that has inexplicably settled into your local pond in north Georgia." Part of the explanation for the armadillo's northward migration is probably climate change.

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."

"The Supreme Court ruled [Monday] that six states cannot, for now, try to limit emissions of greenhouse gases under federal common law. The court ruled 8-0 -- Justice Sonia Sotomayor was recused -- that the Clean Air Act and the Obama administration's efforts to regulate emissions had displaced the states' federal common law argument."

"The first six months of 2011 have brought image after image of human misery and ecological upheaval. Droughts, wildfires, twisters, floods, heat waves, extreme blizzards — just about every natural disaster you can imagine has hit just about every place on the planet."

"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."

"Climate change crept into the discussion of fire management at a Senate Committee on Energy and Natural Resources hearing yesterday, despite Republicans' tiptoeing around the issue."

"A former Republican congressman who is an advocate for action to address climate change plans to launch a new conservative coalition this fall made up of Republicans who, like him, believe that human emissions are triggering global warming and that steps should be taken to stop it."
