The Climate Change and Global Health: Emerging Threats and Evolving Priorities: The Climate Change and Global Health: Emerging Threats and Evolving Priorities

Abstract

Climate change represents one of the most significant global public health challenges of the twenty-first century. Increasing frequency and intensity of heatwaves, food and water insecurity, deteriorating air quality, and the emergence and spread of infectious diseases are increasingly linked to climatic and environmental changes. These impacts disproportionately affect vulnerable populations, including children, older adults, and socioeconomically disadvantaged communities, thereby exacerbating existing health inequities. Addressing these challenges requires robust, evidence-based research to identify population vulnerabilities, quantify health impacts, and evaluate the health co-benefits of climate mitigation and adaptation strategies. Integrating health considerations into national and international climate policies is essential, alongside strengthening climate-resilient health systems through early warning mechanisms, disaster preparedness, and workforce capacity building. A coordinated, cross-sectoral approach is urgently needed to protect human health, reduce inequalities, and safeguard the well-being of present and future generations in the face of ongoing climate change.
