Built and natural infrastructure on military installations and lands face threats from long-term changes in climate and ocean conditions. In the future, there is the potential for changing sea levels and climate to increase both the severity and frequency of more acute conditions, such as those produced by extreme weather events. These threats can directly impact the availability of the installation to train and deploy the force. For example in 2018, Hurricanes Michael and Florence cost DoD a combined $6.6 billion (GAO). This technical session examined on-going research efforts to develop tools and approaches to improve DoD built and natural infrastructure resilience.
