To better understand the structure, development, and function of the climate change communication knowledge domain, we performed time-evolving bibliometric mapping and topic modeling on 2,995 climate change communication publications from Web of Science. Structural and visual representations of scholarship are useful for identifying areas of opportunity and coordinating effort in interdisciplinary and action-oriented knowledge domains. Our analysis reveals a cohesive and dense yet ossified knowledge structure which suggests that while a systems approach is being applied in climate communication, there is a need to explore more constitutive strategies for the communication of climate change.
