WASHINGTON — President Trump said he would announce his decision on whether to pull out of the Paris climate agreement in a Thursday afternoon event in the White House Rose Garden — the same place where President Obama hailed the agreement as "a turning point for our planet."

With typical Trumpian flair for building suspense, the president announced his announcement via Twitter.

The 197-member climate agreement requires every country to establish ambitious targets to reduce greenhouse gasses. But those targets are largely voluntary, and Trump has already made clear that he views environmental regulations as an obstacle to his goal of creating jobs and ensuring energy independence.

Still, the rest of the world is watching to see how far Trump will go in backing out of the accord. His options could range from staying in and renegotiating the terms of the agreement, to exiting the underlying treaty entirely.

But the president has also been known to change his mind, as he did in April with the North American Free Trade Agreement. After anonymous White House officials signaled for days that Trump would withdraw from the trade agreement, the leaders of Canada and Mexico ultimately persuaded him to renegotiate.

Trump has said he's been lobbied heavily by both sides on the climate agreement. On one side is the economic nationalist wing of his White House, advisers such as Steve Bannon who have called climate change a "manufactured crisis" and who once urged "good global warming skeptics" to leave all the lights in their house on in order to protest the Paris talks.

On the other side is an globalist wing led by daughter Ivanka Trump, who persuaded her father to set up a review process to consult with experts and business leaders before making a decision.

That decision will come less than a week after Trump met with world leaders in Sicily, where closed-door discussions included pleas for the United States to stick to the consensus agreed to in Paris in 2015 and consummated last year.

n a separate meeting with Pope Francis last week, the pontiff presented Trump with a gift — a copy of his two-year-old encyclical on climate change known as Laudato Si.

President Obama had framed the agreement as a key test of American leadership in the world.

Under the terms of the agreement, the earliest a nation can formally withdraw is November, 2020 — the same month Trump will run for re-election.
