GOP presidential candidate Jon Huntsman told conservatives Tuesday that he had doubts about the consensus science on manmade climate change -- science he once believed in. He is only the latest GOPer to flip-flop on science. There was a time when Republicans "believed" in science and cap-and-trade was a Republican invention.

"DURBAN, South Africa -- The world's three biggest polluters China, the United States and India refused to move toward a new legal commitment to curb their carbon emissions Tuesday, increasing the risk that climate talks will fail to clinch a meaningful deal this week."

"Back-room negotiations began in earnest Monday on a deal to rescue the only treaty governing greenhouse gas reductions and to launch talks on a broader agreement to include the world's largest polluters: China and other emerging economies, the United States and Europe."

"Environmentalists and other nations say U.S. policy changes raise questions about whether it is committed to substantially cutting emissions and aiding developing nations in their efforts to do so."

GOP presidential candidate Newt Gingrich, who once thought climate change was man-made and required action, has changed his position. He now denies the scientific consensus.

"Is the U.S. leading or blocking progress toward stopping global warming? It's a key question this week as officials from more than 190 countries begin the latest round of negotiations seeking an eventual global climate-protection plan."

"African leaders including Archbishop Desmond Tutu, Jay Naidoo of former President Nelson Mandela's cabinet, and Zwelinzima Vavi, general secretary of the Congress of South African Trade Unions, on Wednesday released an ad calling on Canada to step up the battle against global warming, rather than actively promote the use of its tar sands."
