AI Insight
This commentary argues that climate change functions as a health inequity crisis, as climate-related health impacts like heat exposure, flooding, air pollution, and food insecurity disproportionately harm populations and regions that have contributed least to greenhouse gas emissions. The authors trace these disparities to historical colonial systems of resource extraction and dispossession that continue to shape which communities bear the greatest health burdens from climate change. The piece calls for applying an intersectionality framework to climate and health equity research.
Why it matters
Understanding climate change through an equity lens is essential for developing interventions that address root causes of vulnerability rather than treating all populations as equally affected. This perspective could inform more just climate adaptation policies and health interventions that prioritize historically marginalized communities.
Understand the Science
Climate change is not only a health crisis, but also a crisis of health inequity. Heat, floods, cyclones, air pollution, food insecurity, and population displacement are already reshaping patterns of mortality and morbidity,1 disproportionately harming people and places that have contributed least to climate change.2 These inequities are rooted in colonial histories of extraction, dispossession, and unequal development, which continue to determine whose lives and environments are rendered expendable.
