The purpose of this chapter is two-fold: 1.) Test the effects of climate message frame (damage to nature or damage to public health), message source (liberal or conservative organization), and the use of visual human exemplars (present or absent) in social media messages; and, 2.) Assess the predictive utility of different conceptual frameworks (personification, construal level theory, and moral foundations theory) as explanatory mechanisms for persuasive social media climate message effects. The results of a nation-wide experiment reveal that the use of visual exemplars matters when climate change is framed as an environmental problem, but otherwise message frame, source, and visual exemplar use have little impact on policy attitudes. Further analyses demonstrated that multiple conceptual mechanisms related to the aforementioned theories help explain social media effects on climate change attitudes.
