Two military bases on Guam have been identified as among dozens of installations that a Pentagon report says are susceptible to the adverse effects of climate change.

At Naval Base Guam, recurring flooding limits the capacity for a number of operations and activities involving the Navy Expeditionary Forces, submarine squadrons, telecommunications and a number of other specific tasks supporting mission execution, the January report from the Pentagon states.

"Additionally, recurrent flooding impacts operations and activities of contingency response groups at Andersen Air Force Base, as well as mobility response, communications, combat and security forces squadrons," the report states.

The effects of a changing climate are a national security issue, the report states.

Andersen and the Navy base on Guam are also expected to be adversely affected by drought, the report states.

In addition to rising sea levels, flooding and drought, other military installations also face adverse effects of thawing and permafrost or "desertification," the report states. The report covered a review of military installations under the U.S., European, Pacific and African Commands.

'Effects of a Changing Climate'

Seventy-nine U.S. bases and other military installations were identified in the "Report on Effects of a Changing Climate to the Department of Defense."

The 2019 report and a 2018 version of it recommend efforts to "build a more lethal force, strengthen alliances and attract new partners, and reform the department's processes."
