| Abstract: | Over the past 20 years, there have been dozens of news organization,academic, and nonpartisan public opinion surveys on global warming,yet there exists no authoritative summary of their collectivefindings. In this article, we provide a systematic review oftrends in public opinion about global warming. We sifted throughhundreds of polling questions culled from more than 70 surveysadministered over the past 20 years. In compiling the availabletrends, we summarize public opinion across several key dimensionsincluding (a) public awareness of the issue of global warming;(b) public understanding of the causes of global warming andthe specifics of the policy debate; (c) public perceptions ofthe certainty of the science and the level of agreement amongexperts; (d) public concern about the impacts of global warming;(e) public support for policy action in light of potential economiccosts; and (f) public support for the Kyoto climate treaty. |
