The report underscores the severe risks posed by climate change to global health systems, particularly in low- and middle-income countries. Vulnerable populations, including women, children, and the elderly in high-risk zones, are disproportionately affected. Without adequate preparation, these regions face escalating health crises, including heat-related illnesses, vector-borne diseases, and disruptions to healthcare access. The economic and social costs of inaction are significant, with health systems forced to react to emergencies rather than proactively mitigating risks. The study highlights the importance of integrating climate data into health planning to reduce these vulnerabilities.
