Pentagon Confirms Climate Change Is A National Security Threat, Contradicting Trump

More than a year after President Donald Trump nixed climate change from his administration’s list of national security threats, the Pentagon has released an alarming report detailing how dozens of U.S. military bases are already threatened by rising seas, drought and wildfire.

“The effects of a changing climate are a national security issue with potential impacts to Department of Defense missions, operational plans, and installations,” states the 22-page document, which was published Thursday.

The congressionally mandated analysis looked at a total of 79 military installations around the country. The Defense Department found that 53 sites are currently vulnerable to repeat flooding. Langley Air Force Base in Virginia, for example, has experienced 14 inches of sea level rise since 1930. Additionally, more than half of the 79 bases are at risk from drought, while nearly half are vulnerable to wildfire.

These climate impacts are expected to pose a risk to several other installations over the next two decades, and the report notes that “projected changes will likely be more pronounced at the mid-century mark” if climate adaptation measures are not taken.
