The idea of climate change inspires and reinforces disagreements at all levels of society. Climate change’s integration into public life suggests that there is no evident way of framing and tackling the phenomenon. This brings forward important questions regarding the role of ideology in mediated public discourse on climate change. The existing research literature shows that five ideological filters need to be taken into account to understand the myriad ways in which ideology plays a role in the production, representation, and reception of climate change in (news and entertainment) media: (i) economic factors, (ii) journalistic norms, (iii) political context, (iv) ideological cultures, and (v) citizen decoding. Furthermore, two different interpretations of how ideology precisely serves as a filter of social reality underlie this literature: an interpretation of ideology as an independent variable, on the one hand, and as a constitutive practice, on the other. Moreover, these interpretations underlie a broader discussion in the social sciences on the relation between climate change and ideology and how scholars and activists should deal with it. By considering climate change as a post-ideological issue, a first perspective problematizes the politicization of climate change and calls for its depoliticization to foster consensus and public engagement. In response, a second perspective takes aim against the post-politicization and post-democratization of climate change (resulting from the adoption of the first perspective) for suppressing the role of ideology and, as a result, for stifling democratic debate and citizenship with regard to the climate issue. This latter perspective is in need of further exploration in future research, especially with regard to the concepts of ideological fault lines, ideological hegemony, and ideological strategies.
