Obama's fragile climate legacy
President Barack Obama wants to be remembered as the president who saved the world from climate change. But the 195-nation accord aimed at curbing global warming may be the most fragile of his presidential achievements so far. More than any of his other top accomplishments—economic recovery, health care reform, the Iran deal, all of which involved Congress to some extent—Obama’s environmental legacy rests on the exercise of executive power over the objections of Republican lawmakers.
