A Partisan and Polarized Issue in the United States

Abstract

Climate change has become a politically polarized issue within the past 30 years, as interest groups and certain political leaders sought to dispute the growing scientific consensus about its causes and impacts. This chapter synthesizes a large body of survey, experimental and methodological literature that places the empirical study of South Florida in context. Past survey research has shown conclusively that party identification and ideology are the strongest predictors of climate change beliefs of Americans. Other predictors that are less consistent include demographic characteristics, cultural worldviews and personal experience. Survey and laboratory research has been directed at understanding the processes involved in accepting or denying messages about climate change. Among the findings are that strategically framed messages can shift opinion, that a belief in scientific consensus about climate change may increase acceptance of its reality, that prior beliefs, group identities and cultural worldviews moderate the acceptance of climate change information through motivated reasoning, and that best practices involve describing climate change as a personal risk, using social group norms to convince skeptics, and emphasizing social consensus on the issue. Prior research suggests that a message about environmental risk that is local and specific will be relatively more effective, particularly when the immediate threat is already visible.
