"A report commissioned by the United States Navy concludes that climate change will pose profound challenges for the sea service in coming decades, including a need to secure Arctic shipping lanes, prepare for more frequent humanitarian missions and protect coastal installations from rising seas.
The 15-month study, conducted by the National Research Council, accepts the scientific consensus that the climate is changing and that the effects are being felt now. Of particular consequence to American naval forces – the Navy, Marine Corps and Coast Guard – are the melting polar ice cap, rising seas and increasingly frequent severe storms and droughts that could lead to famine, mass migration and political instability.
The report from research council, an arm of the National Academy of Sciences, builds on previous work by the Pentagon, State Department, the intelligence community and independent research groups that have concluded that climate change is a “threat multiplier” that adds new and unpredictable dangers to global physical and political stability."
