<p dir="ltr">Climate change hazards are becoming more frequent and severe and their impact on Department of Defense installations has become a matter of national security. This thesis investigates the intricate relationship between climate change hazards and the Department of Defense (DoD) by examining the multifaceted impacts of environmental shifts on military operations, infrastructure, and strategic planning. As the global climate continues to undergo unpredictable changes, the DoD faces evolving challenges that extend beyond traditional security concerns.</p><p dir="ltr">The research employs a multidisciplinary approach, integrating environmental science and analysis with military strategy to assess the current and anticipated hazards posed by climate change. As the beginning of a multi-year project, this thesis examines extreme weather events in relation to their potential to disrupt critical military assets and installations in Yuma County Arizona.</p><p dir="ltr">Additionally, decision support systems were created and analyzed as part of this thesis in order to provide Department of Defense decision-makers with a tool to create personalized and up to date visuals and data. This support tool could have positive implications for force readiness, mission effectiveness, and strategic planning, recognizing climate change as a pervasive and dynamic threat.</p><p dir="ltr">The study also delves into the strategic response of the DoD to climate change hazards, evaluating adaptation measures, resilience-building initiatives, and the integration of climate considerations into defense planning processes. By examining historical and future conditions, the research identifies areas where these installations could implement changes in order to enhance climate resilience and efficiency within the defense framework.</p><p dir="ltr">In conclusion, this thesis provides an understanding of the intricate interplay between climate change hazards and national security, focusing on their direct and indirect impacts on two military installations in Arizona. By shedding light on the complexities of this relationship, it contributes to the growing body of knowledge essential for developing adaptive strategies and policies that ensure the readiness and effectiveness of the military in the face of a changing climate.</p>
