Climate change is a global challenge for humanity, and climate action is essential to address its impacts. With the purpose of building a clear theoretical framework for the research field of climate action and to gain a deeper understanding, this paper conducts a bibliometric analysis of 28,457 articles, which were selected from WoS data sources. These articles were analyzed through VOSviewer and CiteSpace, with the aims of exploring publication growth trends and categories, co-authorship analysis, national and regional collaboration, organization cooperation, co-citation journals, citations, keywords, and funding information. Subsequently, a knowledge graph for climate action was constructed, emerging trends were analyzed, and a clear theoretical framework was established. The research outcome offers effective, substantive, and forward-looking suggestions for the sustainable development of climate action.
