Abstract

Climate change is one of the main challenges of our time, yet public support for climate action is lacking. This study scrutinizes the role of the media in educating the public on climate change and examines how media use relates to citizens’ climate-related public opinion. We test two models of opinion formation: the deficit model, which posits that media dissemination of scientific information can enhance climate knowledge, leading to increased climate-friendly attitudes and behavior; and the motivated reasoning model, which suggests that citizens interpret information in a biased manner. Conducted in a context where climate coverage is mostly science-based, our cross-sectional survey provides evidence for both models. The relationship between media use and climate knowledge varies by media type and citizens’ ideology. Additionally, media use influences not only citizens’ cognitions but also their climate predispositions.
