Despite the scientific consensus that global warming is occurring and caused by human activity, a new survey conducted for the Pittsburgh Post-Gazette demonstrates that many Americans remain uncertain about the impact of climate change and the need for government action to address it. Only 41 percent of Americans believe that ‘most scientists agree that climate change is happening now caused mainly by human activities.’
This is contrary to some polls suggesting wide support for steps to counter the phenomenon. David W. Moore, director of the iMediaEthics survey, said the results suggest that, because of flaws in methodology or wording, some other surveys have overstated the degree of public knowledge on the issue, and the intensity of support for measures to curb carbon emissions. [See Mr. Moore’s essay in today’s Forum section, “Climate Partisans.” The poll report is available here, along with a description of the methodology.
