Word of Trump's decision comes a day after the president met with Scott Pruitt, the administrator of the Environmental Protection Agency.
White House aides were divided on the topic and had been deliberating on "caveats in the language" as late as Wednesday, one official said. But the city and county have a number of alternative uses for coal moving forward, a nod to the demand for clean energy sources in an evolving electricity market.
In addition to blaming China for "hurting our air", Trump also previously tweeted, "The concept of global warming was created by and for the Chinese in order to make USA manufacturing non-competitive". They both appeared on Fox News' "Fox & Friends".
Pence called Trump's decision "refreshing". Supporters of the deal say it's not an either-or choice. "In a very real sense, it was a transfer of wealth from the most powerful economy in the world to other countries around the planet", Pence said.
Fox News also cited an unidentified source confirming the withdrawal.
Scientists say Earth is likely to reach more risky levels of warming sooner as a result of the president's decision because America contributes so much to rising temperatures.
Suggesting renegotiating re-entry was not a major priority, he said, "If we can, great". Juncker says, "This notion, 'I am Trump, I am American, America first and I am getting out, ' that is not going to happen".
A senior European Union official said the EU and China would reaffirm their commitment to the pact regardless of what Trump did, and would spell out, during talks Friday in Brussels, how they would meet their obligations. "We certainly will be at the table", she said, "playing a leadership role because we think it's the right thing to do and it makes economic sense".
Those briefed by the White House insisted on anonymity in order to discuss the matter ahead of Trump's announcement Thursday afternoon in the Rose Garden.
While not mentioning the U.S.by name, Chinese Foreign Ministry spokeswoman Hua Chunying tells reporters climate change is a "global challenge" that no country can ignore.
Trump, who was on the end of his first official foreign trip, had asked for more time and said he would make a decision this week.
By abandoning the world's chief effort to slow the tide of planetary warming, Trump was fulfilling a top campaign pledge after weeks of building up suspense over his decision.
The Pruitt team is deciding on whether to initiate a full, formal withdrawal which could take three years or exit the underlying United Nations climate change treaty, which would be faster but more extreme, Axis reported.
Since taking office, however, he has come under pressure from advisers, close allies, corporate CEOs, Democrats and some fellow Republicans to keep the United States in the accord - causing him to rethink and delay his decision.
The United States, under former President Barack Obama, had committed to reduce its emissions by 26 percent to 28 percent from 2005 levels by 2025.
Major U.S. allies, business leaders and even the Pope had urged the U.S.to remain in the deal.
The accord, agreed on by almost 200 countries in Paris in 2015, aims to limit planetary warming in part by slashing carbon dioxide and other emissions from the burning of fossil fuels.
The rumors of a pullout didn't resonate as well as some might expect in Gillette, the hometown of the nation's thermal coal industry, whose citizens by and large voted for Trump because of his pro-coal stance. But he said in response to a question afterward that the United Nations believes "it would be important for the US not to leave the Paris agreement". The decision has no direct impact on major USA regulations on power plants and vehicle rules now aimed at reducing carbon emissions, although those are now under review by Trump as well.
It is absolutely essential that the world implements the Paris Agreement on climate change.
European leaders pushed Trump to stay in the Paris pact during his recent overseas trip, and some of his advisers prefer the US stays committed to the climate accord.
But House Democratic leader Nancy Pelosi of California called it "a stunning abdication of American leadership and a grave threat to our planet's future".
A withdrawal would put the United States in league with Syria and Nicaragua as the world's only non-participants in the Paris agreement. A White House official said the couple instead attended service at synagogue for the Jewish holiday of Shavuot.
