The first trigger to any form of personal and collective change begins with emotions. They influence whether and how our attention is drawn to stimuli, how we reflect upon those stimuli, and how we choose courses of action. Emotions are thus at the center of social responses to climate change. We offer a selective, interdisciplinary review of emotions research to inform the development of a hypothetical emotion-cognition model of climate change response, followed by exploration of the emotional precedents supporting three prevailing behavioral responses which support inaction: apathy, denial, and withdrawal. We then review research that can inform emotion triggers to pro-climate adaptive and mitigative action. We conclude with a discussion of two key research needs: intersectionality and interdisciplinarity. Addressing these needs will enhance our ability to respond to the climate emergency.
