Trump to Cancel Obama's Policies Aimed at Paris Climate Pledge

President Donald Trump is moving aggressively to undo policies designed to keep the carbon-cutting promises the U.S. made alongside nearly 200 other countries in Paris, while stopping short of a decision to formally withdraw from that landmark climate accord. Trump will sign an executive order Tuesday that begins unraveling a raft of rules and directives to combat climate change, which President Barack Obama wove into the fabric of the federal government as he made addressing the issue a centerpiece of his second term.
