https:/crsreports.congress.gov July 26, 2019Military Installations and Sea-Level Rise The Department of Defense (DOD) manages more than 1,700 military installations in worldwide coastal areas that may be affected by sea-level rise. These installations support DOD readiness and operations including naval vessel embarkation and disembarkation, amphibious training, and special operations forces training. Military installations on and near the coast are at risk for high-tide and storm surge flooding amplified by sea-level rise. Congress may choose to assume a role in preparing military installations for sea-level rise based on its authority in fiscal and national security matters. Sea-Level Rise and Climate Change Global climate observations from the National Oceanic and Atmospheric Administration (NOAA) show trends of increased surface, air, and ocean temperatures that correlate with sea-level rise. The U.S. Global Change Research Program (USGCRP) reports that global mean sea level (GMSL) has risen by approximately 7-8 inches since 1900; further, GMSL has risen 3 inches of GMSL since 1993 (see CRS Report R43229, Climate Change Science: Key Points, by Jane A. Leggett). NOAA identifies
