16 pages., via online journal., The 2018 report from the Intergovernmental Panel on Climate Change warns that Earth’s temperatures may soon reach a tipping point that threatens humanity’s future. Scientists from many disciplines agree that anthropogenic climate change is a serious problem yet many Americans remain skeptical of the existence, causes, and/or severity of climate change. In this article, we review recent research on climate change communication focusing on audience variables and messaging strategies with the goal of providing communication practitioners research-based recommendations for climate change message design. Factors that influence audience acceptance and understanding of climate science include: demographic variables (such as political party affiliation, religious orientation, and geographic location), as well as brief sections on misinformation, and beliefs in pseudoscience. Keys to effectively construct climate messaging are discussed including: framing strategies; reducing psychological distance; emotional appeals; efficacy cues; weight-of-evidence/ weight of expert reporting; inoculation/correcting misinformation; and separating science from conspiracy theories. Evidence-based strategies are critical in giving science communicators the tools they need to bridge the gap between the scientific community and the at-risk public.
29 pages, via online journal, Using an online between-subject experiment, this study tested the effects of message framing (gain vs. loss), reference point (self vs. other), and modality (text vs. infographics) in the scenario of recycling promotion. The findings identified that modality determines under what circumstances message strategies make a difference in risk perception and optimistic bias. In particular, only when paired with infographics and other-referencing point are loss-framed messages more effective than gain-framed messages in increasing risk perception and reducing the self-other gap in perceived benefits. Moreover, risk perception variables and the self-other risk perceptual gap were significant predictors of promoted behavioral intentions.
