Relationships among conspiratorial beliefs, conservatism and climate scepticism across nations

Abstract

Studies showing that scepticism about anthropogenic climate change is shaped, in part, by conspiratorial and conservative ideologies are based on data primarily collected in the United States. Thus, it may be that the ideological nature of climate change beliefs reflects something distinctive about the United States rather than being an international phenomenon. Here we find that positive correlations between climate scepticism and indices of ideology were stronger and more consistent in the United States than in the other 24 nations tested. This suggests that there is a political culture in the United States that offers particularly strong encouragement for citizens to appraise climate science through the lens of their worldviews. Furthermore, the weak relationships between ideology and climate scepticism in the majority of nations suggest that there is little inherent to conspiratorial ideation or conservative ideologies that predisposes people to reject climate science, a finding that has encouraging implications for climate mitigation efforts globally.
