Climate Communication, Public Health, and Social Media: Examining the Role of Health Agencies in Addressing the Impacts of Climate Change on Human Health.

The impacts of climate change on human health are a critical public health concern, with previous studies highlighting its clear effects on well-being. Understanding how state and territorial health agencies (STHAs) are addressing these emerging risks is important. This study conducted 26 in-depth interviews across the U.S. to explore the perceptions and communication strategies of STHA officials regarding climate change's impact on human health. Additionally, the study sought to identify the primary challenges faced by these officials to effectively communicate the impacts. Thematic analysis of the data revealed three major themes: community building and coalitions, climate denialism on social media, and misinformation about climate change and its effects on human health. These findings offer valuable insights for climate change and public health communication. The importance of the STHAs' development of technical and informational capacity to effectively communicate climate-related risks and threats is emphasized.
