BREAKING: Trump Pulls U.S. Out Of Historic Paris Accord Aimed At Curbing Climate Change

President Donald Trump announced his decision to withdraw the U.S. from the Paris climate accord Thursday, calling the international pact to curb climate change "unfair" to the U.S.

Trump's decision — which fulfills one of his campaign promises — leaves the U.S. at odds with almost every other country on Earth; according to CNN, the only other countries that don't support the climate deal are Nicaragua and Syria.

“In order to fulfill my duty to protect America and its citizens the United States will withdraw from the Paris Climate Accord," Trump said during a reality show-esque press conference at the White House Rose Garden. 

“Not only does this deal subject our citizens to harsh economic restrictions, it fails to live up to our environmental ideals," Trump added. "The bottom line is that the Paris Accord is very unfair at the highest level to the United States ... I was elected to represent the citizens of Pittsburgh, not Paris."

The Paris accord was adopted in December 2015, with 195 nations voluntarily agreeing to its taxing system in an effort to cut down on greenhouse gas emissions and curb climate change. 

At the time, then-President Barack Obama called the deal one of his most important achievements as commander in chief, according to CBS Miami. 

Trump dismantled another one of Obama's major climate change efforts in March when he signed an executive order withdrawing and rewriting Obama's Clean Power Plan. That legislation had shuttered hundreds of coal-fired power plants and replaced them with wind and solar farms in an effort to limit carbon dioxide pollution.

Chief strategist Steve Bannon and EPA administrator Scott Pruitt were the loudest anti-Paris accord voices among Trump's team. Senior adviser Ivanka Trump, Secretary of State Rex Tillerson, and chief economist Gary Cohn were on the other side, according to CNN, and had urged the president to change the U.S.' commitments to the deal without completely withdrawing from it.

The process of the U.S.' withdrawal from the Paris accord won't wrap up until November 2020, so it'll likely be a major issue in the next presidential election.
