The Department of Defense (DoD) has warned for years that climate change is a national security threat and, despite President Trump’s orders, the agency continues to take steps to help the military navigate and prepare for the impacts of a warming planet. As Military Times reports, the Pentagon is plowing ahead with its 2014 “Climate Change Adaptation Roadmap” even though Trump issued an executive order in March seeking to reverse Obama-era federal climate and clean energy initiatives. Unlike his White House boss, Defense Sec. Jim Mattis does not believe that climate change is a “hoax” invented by the Chinese.
