Over the past twelve months, 12 senior officials at the US Defense Department (DoD) have raised concerns about, and recommended actions to address, the security implications of climate change, both due to its effect on military infrastructure, readiness and operations, and its broader geostrategic implications for the United States. This includes Secretary of Defense, James Mattis; Vice Chairman of the Joint Chiefs of Staff, General Paul J. Selva; Secretary of the Navy, Richard Spencer; Chief of the National Guard Bureau, General Joseph Lengyel; Assistant Secretary of Defense for Energy, Installations and Environment (IE&E), Lucian L. Niemeyer; Assistant Secretary of the Army for Civil Works, R.D. James; Assistant Secretary of the Navy for Installations, Energy, and the Environment, Phyllis L. Bayer; Assistant Secretary of the Air Force for Installations, Environment, and Energy, John Henderson; Assistant Commandant of the Marine Corps, General Glenn Walters; Vice Chief of Naval Operations, Admiral Bill Moran; Air Force Vice Chief of Staff, General Stephen Wilson; and Army Vice Chief of Staff, General James McConville. The DoD also produced a survey report on the matter in January of this year. Below is a chronological list of written and verbal statements by these defense officials, as well as links to DoD reports and other government documents covering the climate-military nexus, that have been released during this Administration thus far.
