The Pentagon report focused on 79 installations across the armed services. It said 53 installations currently experience recurrent flooding, 43 face drought, 36 are exposed to wildfires, six are undergoing desertification and one is dealing with thawing permafrost.
More installations will feel those climate stressors in the future, with 60 sites projected to see recurrent flooding, 48 confronted hurt by drought and 43 threatened at risk of wildfires.
The report builds on a number of other Pentagon reports that have called climate change a “threat multiplier” that can alter DOD priorities, such as mass migration and humanitarian aid missions fueled by extreme weather events.
The fingerprints of climate change can disrupt everyday military operations, the report said.
