It is therefore essential to more fully investigate social-psychological responses to climate information and messaging if we are to prompt, support, and sustain pro-environmental behaviors. Yet consideration of these responses is typically absent from interdisciplinary environmental study designs. Of specific relevance is research using social psychology’s Terror Management Theory (TMT) showing that people’s efforts to repress mortality salience or awareness significantly influence their attitudes, beliefs, and behaviors. Research on mortality salience’s influence on climate change beliefs is progressing, but to date a systematic scoping review of the literature has been unavailable. Here, we provide such a review. We propose that TMT insights and methods must be better integrated into research designs to guide climate communications and to generate the comprehensive cultural and behavioral changes needed to address societies’ climate problems. We introduce a methodological framework for interdisciplinary researchers to incorporate TMT into their research designs and help practitioners anticipate how their mortality-laden messaging could trigger unintentional social-psychological responses that degrade climate communication strategies.enclimate changeemotionpro-environmental behaviormortality awarenessresearch methodssustainabilityterror management theoryArticle
