Climate Change and Global Health: An Interconnected Review

Abstract

This comprehensive review explores the multifaceted impacts of climate change on global health, emphasizing the interconnectedness of environmental changes with vector-borne diseases, food security, and public health structures. As global temperatures rise and climatic patterns shift, there is an increased prevalence of vector-borne diseases such as malaria, dengue, and Zika, which are profoundly influenced by altered environmental conditions that favor vector proliferation and extend their geographical range. Simultaneously, food security is severely threatened as climate change impacts crop yields, livestock health, and fisheries, essential components of the global food supply chain. The review further discusses public health responses, detailing both the existing health risks exacerbated by climate change and the strategic adaptations that countries have implemented to mitigate these risks. Through an examination of various national and global strategies, from improved surveillance systems to disaster preparedness and adaptive agricultural practices, the article highlights the necessity for integrated research, policymaking, and practice to address these global challenges. It calls for enhanced international cooperation and innovation to effectively manage the health effects of climate change, ensuring a resilient approach to safeguarding global health in the face of environmental uncertainties.
