The relationship between the mass media and climate change governance remains largely unexplored in the academic literature. In this paper, I argue that the media does influence outcomes on climate change. I provide an overview of media accounts on climate change, the factors which influence the reporting, and how the media can shape public opinion on the issue. Throughout, I treat the mass media as a mechanism of information diffusion and argue for its agenda-setting power on the climate change issue. Finally, I forward an original theoretical model whereby freedom of the press influences climate change governance. I argue that a freer media is more likely to transparently report the scientific consensus and thus take an implicitly normative stance in favor of climate change action. I then corroborate the model with multivariate regression analysis. The regression output finds that freedom of the press may correlate better with climate change activism than originally thought.
