A recent report for the Gallup survey organization by Oklahoma State sociologist Riley Dunlap backs up what I have been arguing at this blog and in various articles regarding the “Two Americas” of global warming perceptions. Following the lead of their preferred party’s elected officials and leaders, Democrats continue to grow more concerned about global warming while Republicans remain relatively unconcerned, dismissive of the science, and distrustful of news reports. The full report is a must read. See in addition this recent study (PDF) I did analyzing two decades of public opinion trends on global warming and this column on breaking the partisan-perceptual gridlock, titled “Going Beyond Gore’s Message.”
