Post-truth messages are hegemonic forms of communication intentionally designed to create false narratives that perpetuate power and marginalize others. These messages make differentiating fact from fiction difficult. Students are especially susceptible to believing and internalizing post-truth messages due to their high level of interaction with social media and the neoliberal period in which they have been raised. One type of post-truth message that has become especially prevalent is climate change denial messages that advance a neoliberal agenda. This article will apply tenets of critical communication pedagogy (CCP) as a means by which to recognize messages that deny climate change as examples of post-truth.
