The health impacts of climate change are expected to disproportionately affect populations in developing countries, where health systems are less equipped to manage the challenges. Vulnerable groups, including children, the elderly, and those with pre-existing health conditions, are at heightened risk. Rising temperatures and changing weather patterns exacerbate the spread of vector-borne diseases like malaria and dengue, while extreme weather events threaten food security and access to clean water. Air pollution, driven by greenhouse gas emissions, remains a critical concern, contributing to millions of premature deaths annually.
