The film led moviegoers to have higher levels of concern and worry about global warming, to estimate various impacts on the United States as more likely, and to shift their conceptual understanding of the climate system toward a threshold model. Further, the movie encouraged watchers to engage in personal, political, and social action to address climate change and to elevate global warming as a national priority. Finally, the movie even appears to have influenced voter preferences. These results demonstrate that the representation of environmental risks in popular culture can influence public attitudes and behaviors.
