Where does US climate policy stand in 2019?:

The Paris Climate Agreement came out of the 21st session of the United Nations Climate Change Conference in December 2015, and went into force on November 4, 2016. The United States was one of the principal drivers of the compromise, and President Obama hailed it as “a tribute to American leadership.” As a candidate for president, Donald Trump criticized the agreement as a bad deal for the American people and pledged to withdraw the United States if elected. In June 2017, he announced he would be following through with that promise, though he also (confusingly) said he would immediately start negotiations to reenter the climate accord on better terms.
