The U.S. military has recognized climate change as a national security threat. Over the past three decades, installations across the country have experienced infrastructure damage, personnel evacuations, and millions or billions in rebuilding or repair costs. This Article argues that most military facilities are woefully unprepared for these impacts; to expedite action, it calls for a focus on expanding Other Transaction Authority (OTA) for infrastructure-related procurement, as well as specific measures, mandates, and responses. The Article examines recent devastating weather events across Air Force installations in Florida and California. It then discusses recent laws on environmental response, with a focus on the National Defense Authorization Acts and specific provisions for infrastructure, facility, and related environmental measures, and highlights various directives, plans, and spending behavior. It concludes by proposing top-down solutions for speeding procurement and broadening use of OTAs.

As the prospects of significantly mitigating climate change through emissions reductions become dimmer, the critical necessity of adaptation has become clearer, with failure-to-adapt litigation possibly playing an important role in bringing adaptation measures to pass. Based on a review of every adaptation-related case in the U.S. Climate Litigation Database maintained by the Sabin Center for Climate Change Law, this Article offers the first comprehensive assessment of failure-to-adapt litigation in the United States. It finds that such cases have proliferated in this country over the past decade, but that the lawsuits so far filed have sought specific, incremental, and relatively small-scale adaptation measures rather than systemic, large-scale, coordinated action. The Article’s central finding is that failure-to-adapt litigation in the United States has so far been only modestly successful: most suits have failed, but a significant minority have succeeded. Failure-to-adapt litigation succeeds frequently enough to make it an important, and perhaps underutilized, tool for bringing about much-needed adaptive measures in the United States.
