Science-Consistent Climate Health Beliefs As Predictors of Climate Behaviors and Support for Inflation Reduction Act Provisions and a Carbon Emissions Tax.

Abstract

Understanding the factors associated with acceptance of climate action is central in designing effective climate change communication strategies. An exploratory factor analysis of 12 science-consistent beliefs about the existence, causes, and consequences of climate change reveals three underlying factors: climate change [a] is real and human caused, [b] has increased the frequency of extreme weather events, and [c] negatively affects public health. In the presence of demographic, ideological, and party controls, this health factor significantly predicts a 3-6 percentage point increase in respondents' [a] willingness to advocate for climate change; [b] reported personal pro-climate behaviors; and [c] support for government policies addressing climate change. These results are robust when controlling for respondents' underlying belief in the existence and causes of climate change, respondent worry, self-efficacy, and respondent belief that extreme weather events and heat waves are increasing. These findings suggest ways to bolster public support for climate policies that may otherwise be at risk.
