Climate change significantly influences national security policies as governments recognize its impact on stability and resource availability. Increased natural disasters, resource scarcity, and population displacements linked to climate change can exacerbate conflict and instability. As a result, nations are integrating climate considerations into their security strategies, evaluating how environmental changes affect military readiness and humanitarian responsibilities. Policies may focus on mitigating risks, enhancing resilience, and promoting international cooperation to address climate-related threats. Thus, climate change emerges as a critical factor in shaping comprehensive security frameworks and diplomatic engagements on a global scale.
