President Trump is preparing to establish a panel to examine how climate change affects national security, and will include a White House adviser whose views are sharply at odds with the established scientific consensus that human-caused global warming poses a threat to the nation’s economy, health and security.

President Donald Trump’s decision to withdraw from the Paris climate agreement has come under attack from elected officials across the United States and the CEOs of some of America's biggest companies. But it’s also likely to cause anger and unease at a surprising place: the Pentagon. That’s because some of the Defense Department’s top officials have already expressed their fears that a warming planet poses serious threats to the US. Defense Secretary James Mattis told the Senate Armed Services Committee that climate change would make the world less stable and require the entire government to curb it.
