Seeing is more than believing: Personal experience increases climate action.

Although global warming is a serious problem that influences numerous people worldwide, individuals are still reluctant to change their behaviours. The present research investigates how local hot temperatures affect climate action in non-Western groups. In Study 1, an analysis of temperature and information acquisition by Shanghai residents in 122 days found that heat increased attention and awareness of climate change. In Study 2 and Study 3, participants who were primed with heat-related perceptions were more likely to take climate action in private and public spheres. In Study 4, we further identified that people who experienced hot temperature events increased their beliefs and efficacy about climate change, which in turn motivated them to take more climate action. Importantly, the mediating effects were significant both in the manipulation of heat and real-world settings. Consistent with our theoretical perspective, seeing is more than believing because personal experience increases climate action by fostering climate change beliefs and efficacy.
