Public understanding of the politics of global warming in the news media: the hostile media approach.

This study uses the politics of global warming in the US to investigate an affective mechanism of hostile media perception and the democratic consequences of such perception, in an effort to delineate audience and journalistic barriers to stimulating urgent concern about climate change. The study confirms that partisanship played a significant role in perceptual differences with regard to media bias in an important area of science journalism--climate change. News consumers' anger perception was tested as a mediator in seeking an affective mechanism of hostile media perception. Hostile media perception has important democratic consequences in that it is positively associated with individuals' trust in news coverage of global warming and with selective media use.
