Climate Change-Induced Health Crises: Integrating Emergency Preparedness into Global Health Security Agendas

Climate change has emerged as one of the most pressing global threats to public health in the 21st century. Rising temperatures, extreme weather events, air pollution, and shifting disease vectors are increasingly linked to morbidity and mortality across regions. While the health consequences of climate change are becoming more apparent, the integration of climate-responsive emergency preparedness into national and international health security agendas remains fragmented and insufficient. This article explores the intersection between climate change and global health security through a policy-oriented lens, emphasizing the need for structured emergency preparedness strategies. We present a comprehensive review of recent empirical data from 2020 to 2025, using case studies from both the European Union (France, Germany) and key non-EU countries (Japan, Israel, United States) to illustrate diverse national responses. Our methodology combines qualitative policy analysis with comparative health impact assessment, drawing on datasets from WHO, ECDC, IPCC, and The Lancet Countdown. We identify critical gaps in current frameworks, including underfunded health adaptation plans, unequal global response capabilities, and weak institutional coordination. A conceptual model is proposed to systematically integrate climate-induced health risks into emergency preparedness protocols, aligned with global security principles. The findings underscore the urgency of reshaping public health policies to incorporate proactive, climate-resilient preparedness mechanisms. Based on the comparative case studies and international benchmarks, we offer actionable policy recommendations tailored for multilateral health governance, including WHO, the Global Health Security Agenda (GHSA), and the EU’s Health Union. This research contributes an original, interdisciplinary framework for integrating climate-sensitive health crisis response into global security planning, offering a pathway for future resilience.
