Bush Warns Caution on Climate Bill

President Bush weighed in against a Senate bill that would require dramatic cuts in climate-changing greenhouse pollution, cautioning senators "to be very careful about running up enormous costs for future generations of Americans." Bush, during a White House event that focused on keeping taxes low, said the Senate bill "would impose roughly $6 trillion in new costs on the American economy." Bush, who has favored voluntary efforts and technology innovation to address global warming, did not say how the $6 trillion figure he cited was arrived at.
