NAS Report For Defense Dept: Prepare Now For Migrations, Sea-Level Rises, Epidemics, Drought
The Pentagon was warned on Friday to stand guard against "climate surprises" which could throw off its efforts to secure America's future. An expert report, prepared for the intelligence community by the National Academy of Sciences, warns that the security establishment is going to have start planning for natural disasters, sea level rise, drought, epidemics and the other consequences of climate change.
The Pentagon already ranks climate change as a national security threat, putting U.S. troops in danger around the world and adding fuel to existing conflicts. More than 30 U.S. bases are threatened by sea level rise. It has also identified potential new danger zones, such as sub-Saharan Africa.
The military is also working to cut back on its fuel costs in an age of budget austerity, by installing solar arrays and wind turbines, and monitoring electricity use. But Friday's report suggests strategic planners are going to have make sweeping adjustments to their planning to take account of climate change over the next decade and beyond.
Current scenarios could be thrown completely askew by "climate surprises," the report said. These could be a single catastrophic event — such as a food price shock — or a cascade of reactions that could ultimately put America at risk. "It makes sense for the intelligence community to apply a scenario approach in thinking about potentially disruptive events," the report said. "It may make sense to consider the security implications of two or three more plausible trends as a way to anticipate risks."
