Sept. 7 News: Climate Change Makes An Appearance At Political Conventions — But Is It More Than A Cameo?

After being left out in the cold all year, global warming is making a reappearance on the campaign trail. President Obama, who campaigned aggressively in 2008 on the promise of fighting climate change, has barely mentioned the subject during this campaign, despite a summer of record heat and drought and news reports linking such extreme weather events to increases in greenhouse gases.

But on Thursday night, under the spotlight at the Democratic National Convention in Charlotte, just two months from the general election, Obama made his most high-profile mention of the controversial issue this year.

“And yes, my plan will continue to reduce the carbon pollution that is heating our planet — because climate change is not a hoax,” Obama said. “More droughts and floods and wildfires are not a joke. They’re a threat to our children’s future. And in this election, you can do something about it,” he said, to a sustained ovation.

Until now, Obama’s advisers calculated that in a campaign centered on the economy, a pledge to save the environment by cutting carbon pollution would fall flat — and create a target for Republican attacks. But Thursday’s remarks could signal a new willingness to address a crucial public-policy issue which both campaigns have until now avoided.

President Barack Obama’s effort to develop renewable power sources and persuade Congress to adopt a long-term energy policy will be priorities should he win a second term, his top climate and energy aide said. [Businessweek]
