Public Engagement with Climate Change and Health: A Global Literature Review

With the impacts of climate change on health becoming increasingly severe and far-reaching, effective communication to diverse audiences is more crucial than ever. This review analyzes 93 studies published between 2000 and 2023 on public understanding and responses to information about climate change and health. We synthesize research on public perceptions of climate change and health, responses to health-framed climate information, and information about climate and health risks and solutions, and the depolarizing potential of health messaging. Our findings suggest that conveying the health relevance of climate change holds significant potential for enhancing public engagement and building support for climate action. Additionally, we identify research gaps, particularly in understanding how different demographic audiences perceive health-related climate information and suggest directions for future studies. This synthesis of international research provides valuable insights into how different populations perceive and react to health-related climate information, highlighting the importance of targeted and effective communication strategies in addressing the climate crisis. The findings and summaries in this review can serve as valuable tools for evidence-based initiatives to address the critical issue of climate change and its profound implications for public health.
