President Obama issued a new policy directive Wednesday to consider the effects of climate change in developing national security policy and planning across all major security agencies and the military.

“Today, President Obama signed a Presidential Memorandum on Climate Change and National Security, establishing a policy that the impacts of climate change must be considered in the development of national security-related doctrine, policies, and plans,” the White House said. “To achieve this, 20 federal agencies and offices with climate science, intelligence analysis, and national security policy development missions and responsibilities will collaborate to ensure the best information on climate impacts is available to strengthen our national security.”
