Effectively fighting global warming requires large groups to engage in concerted action. In the present review article we aim to understand how human appraisals and responses to the challenge of climate change are shaped by social identities (i.e. people’s membership in specific social groups). We first describe the recent Social Identity Model of Pro-Environmental Action (SIMPEA), linking social identity theorizing to the study of climate action. Then, we review research on how collective climate action is driven by social identification, ingroup norms, group-based emotions, and collective efficacy beliefs. Finally, we focus on how very inclusive social identities (spatially or temporally), such as global identification, may provide a unique opportunity to advance interventions fostering people’s climate action.

要有效地应对全球变暖，就需要大型团体共同采取行动。在这篇综述文章中，我们旨在了解社会认同（即特定社会群体中的人们的身份）如何塑造人类对气候变化挑战的评估和回应。我们首先描述最近的亲环境行动的社会认同模型（SIMPEA），将社会认同理论与气候行动的研究联系起来。然后，我们回顾了关于社会认同，群体内规范，基于群体的情感和集体效能信念如何驱动集体气候行动的研究。最后，我们关注于具有包容性的社会身份（空间或时间上的身份），例如全球身份识别，如何提供独特的机会来推进促进人们采取气候行动的干预措施。
