Mitt Romney: Humans contribute to global warming - Political Hotsheet - CBS News Romney reportedly said Friday that he believed the United States as well as foreign nations need to "reduce our emissions of pollutants and greenhouse gases," saying they "may be significant contributors" to climate change. As Reuters notes, one of 2012 GOP Romney's rivals, former House speaker Newt Gingrich, said last week that the push to address climate change is "the newest excuse to take control of lives" by "left-wing intellectuals." Gingrich had previously suggested that "our country must take action on climate change." Gingrich is not the only Republican presidential contender to shift on climate change issues. Former Utah Gov. Jon Huntsman said in 2007 that "it's time for Congress to act by capping greenhouse gas pollution," but he now says it isn't the time to address the issue. And former Minnesota Gov. Tim Pawlenty has backed off his previous support for cap-and-trade energy legislation, saying he had been wrong in once calling for a cap on carbon emissions. --- So one guy hedges, and all the rest backpedal to tea-bagger stupidity.
