Perceived personal experience of climate change was positively related to agreement with the new ecological paradigm (β = 0.36), awareness of consequences (β = 0.26), ascription of responsibility (β = 0.25), and personal norm (β = 0.20). Generally, perceived personal experience of climate change mediated the relationship between traditional media, social media, and interpersonal sources and each type of climate change belief. This suggests some types of information, but not all, offer vicarious experiences of an environmental phenomenon that largely escapes direct perception. In addition to those theoretical implications, this work has practical implications for audience segmentation and climate change communication.
