Could climate change negatively impact the defense installations important to companies and communities in your state? Chances are good that it already does. A new Department of Defense report to Congress reveals all but six of 79 mission assurance priority installations within DOD are experiencing negative climate change effects such as recurrent flooding, drought, desertification, wildfires, or thawing permafrost. Some of the installations are experiencing multiple effects. Additionally, four of the final six are expected to see negative climate change impacts within the next 20 years, or, as the report states in “only” 20 years.
