Trump signed an executive order that begins the process of withdrawing from the Paris Climate Agreement, which he also did during his first term.

When Trump announced the U.S. withdrawal from the climate agreement in 2017, the move reverberated around the globe. Nearly 200 nations had committed to reducing greenhouse gas emissions under the pact when it was created in 2015, and they had set ambitious targets to keep global temperature rise well below 2°C, and ideally below 1.5°C.

WASHINGTON — The 2015 Paris climate agreement is not the boogeyman that punishes the United States that critics such as President Donald Trump claim. But it hasn’t quite kept the world from overheating either.
