Abstract: What are the links among climate change, epidemics, and socioeconomic inequality? Although the recent pandemic has focused attention on the effects of epidemics on economic outcomes, and a separate literature in climate science and environmental health has linked global environmental change to an increase in infectious disease epidemics, there is relatively little work connecting these two strands of literature. We explore the links among climate change, epidemics, and group-based inequality by first reviewing the scientific literature modeling the effects of global warming on infectious disease epidemics. We highlight the ways in which climate variables (such as temperature, precipitation, and wind speeds) and adaptive human behavior (such as migration) in response to climate events may facilitate the spread of infectious disease. We then examine the effects of climate-induced epidemics on gender inequality using evidence from the African meningitis belt. The results show that epidemics can worsen outcomes for groups in already economically precarious circumstances, thereby widening group-based socioeconomic inequality. Effective policies to combat the negative effects of epidemics must be mindful not to increase existing group-based inequalities and should aim to reduce these inequalities by minimizing damage for members of the most marginalized groups in societies.
