A Review of the Impacts of Climate Change on Emergency Medicine: Increased Natural Disasters and Their Related Health Impacts

Background: Climate change is an imminent public health crisis that has significantly impacted emergency medicine by increasing the frequency and severity of natural disasters. Anthropogenic greenhouse gas emissions have intensified heatwaves, hurricanes, and wildfires, leading to heightened risks to human health and increased burdens on emergency medical services (EMS). Aim: This review aims to synthesize current evidence on the health consequences of climate-induced disasters and to provide actionable recommendations for enhancing the resilience, equity, and effectiveness of EMS in the face of escalating climate-related challenges. Methods: A comprehensive literature review was conducted, focusing on studies addressing the direct and indirect health impacts of natural disasters exacerbated by climate change, the vulnerabilities of at-risk populations, operational challenges faced by EMS, and adaptive strategies including disaster preparedness, public health integration, telemedicine, and predictive modeling. Results: Natural disasters result in direct health effects such as traumatic injuries, heat-related illnesses, and respiratory diseases, as well as indirect impacts including psychological disorders, infectious disease outbreaks, and disruption of chronic disease management. Vulnerable groups—such as impoverished individuals, those with pre-existing conditions, and the elderly—experience disproportionate adverse outcomes due to limited access to resources and healthcare. EMS face operational challenges including facility flooding, resource scarcity, and logistical barriers, which hinder timely and effective response. Adaptive measures like enhanced disaster preparedness, integration of EMS with public health systems, and technological innovations such as telemedicine and predictive analytics have demonstrated potential in mitigating these challenges. Conclusion: To address the growing public health threat posed by climate change, EMS systems must adopt robust, equitable, and innovative strategies. Strengthening disaster preparedness, fostering cross-sector collaboration, and leveraging technology are critical to improving emergency care delivery amidst increasing climate-related disasters.
