Climate change is a threat to wildlife and the environment, but it also one of the most pervasive threats to human health. The goal of this study was to examine the relationships among dimensions of health literacy, patient education about global warming and climate change (GWCC), and health behaviors. Results reveal that patients who have higher levels of health literacy are more likely to engage in mitigation behaviors. An empirically based set of recommendations for providers to educate patients about the health risks of global warming and climate change is proposed. (Contains 2 tables.)
