This paper examines the discourse, news values, and linguistic devices utilized by six news outlets across the political spectrum - InfoWars, Fox News, BBC News, The Wall Street Journal, The New Yorker, and Democracy Now! - in their reporting related to climate change. In particular, the analysis of headlines from each outlet highlights differences and commonalities in their reporting.

The results showcase the common utilization of negative valence and superlativeness values, between all groups, as well as greater use of greater intensification and mentions of elites, groups, and institutions in the more politically extreme sources. Right-leaning outlets were more likely to use extreme language and negative role labels when addressing climate activists and exhibited increased climate change denial. Center-group news sources preferred an overall measured approach with a lesser use of force graduation. All outlets lacked personalization or mention of precise recent events positioning them in time.
