Climate change poses a grave threat to national security that requires urgent action. Rising sea levels, extreme weather events, and environmental degradation are damaging military infrastructure and hindering operations. Displacement of populations due to climate impacts like drought and resource scarcity is fueling instability and conflict globally. Competition for dwindling resources and efforts at decarbonization risk exacerbating geopolitical tensions. This dangerous situation necessitates a comprehensive strategy to curb greenhouse gas emissions and safeguard critical defense capabilities from climate threats. Transitioning to clean energy must be prioritized alongside enhancing infrastructure resilience and preparing for climate-driven humanitarian crises. Protecting national security demands aggressive measures to prevent further warming and adapt to unavoidable climate change impacts already underway.
