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.

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

The president on Monday announced his intention to withdraw the country, for the second time, from the global emissions reduction pact.
