Partisan split on global warming science

Nearly two-thirds of Americans want the federal government to regulate the release of greenhouse gases from sources such as power plants, cars and factories, according to a new Washington Post-ABC News poll. But when it comes to the science behind global warming, those surveyed split sharply along partisan lines. Only 20 percent of Republicans think most scientists agree that global warming in happening, compared with 55 percent of Democrats. And 58 percent of Republican put little or no faith in what scientists say about the environment, while only 23 percent of Democrats have such doubts.
