Effectively reducing climate change requires dramatic, global behavior change. Yet it is unclear which strategies are most likely to motivate people to change their climate beliefs and behaviors. 11 expert-crowdsourced interventions were tested on four climate mitigation outcomes: beliefs, policy support, information sharing intention, and an effortful tree-planting behavioral task. The effects of each intervention differed depending on people’s initial climate beliefs. The findings suggest that the impact of behavioral climate interventions varies across audiences and target behaviors.
