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. Former six-term Rep. Bob Inglis (R-S.C.) said he hopes his coalition will become a factor in the 2012 presidential and congressional elections -- and beyond. He said the view embraced by many Republicans that human emissions are not a major contributor to global warming is out of step with what it means to be a conservative, given that most scientists say the reverse is true.
