WASHINGTON — A government report released Wednesday said climate change is likely to pose a significant national security challenge for the U.S. over the next two decades by heightening social and political tensions, threatening the stability of some countries and increasing risks to human health. In conjunction with the report, President Barack Obama signed a presidential memorandum that orders federal agencies to account for climate change's impacts when developing national security policy. The White House said there is an increasing need for collaboration among scientists and the intelligence and national security communities. "The impacts of climate change on national security are only going to grow," said Dr. John Holdren, director of the White House Office of Science and Technology Policy. The report said that over the next five years, the security risks for the U.S. linked to climate change will arise primarily from extreme weather events and water shortages.
