Last week, President Trump announced that the United States would withdraw from the Paris climate agreement. But it will take more than one speech to pull out: Under the rules of the deal, which the White House says it will follow, the earliest any country can leave is Nov. 4, 2020. That means the United States will remain a party to the accord for nearly all of Mr. Trump’s current term, and it could still try to influence the climate talks during that span.

So the next four years will be a busy time for climate policy. Mr. Trump’s aides plan to keep working to dismantle domestic climate programs like the Clean Power Plan. And the world’s nations will meet regularly to hash out details of the Paris agreement, even as the United States’ exit looms. Here is what comes next.

November 2017

Negotiators for 195 nations will meet in Bonn, Germany, to discuss how to carry out the Paris agreement. Every country has already submitted an initial pledge for curbing greenhouse gas emissions. But officials now have to write rules for monitoring and verifying those pledges.

Technically, the United States is still the co-chair of a key committee on transparency measures. In the past, American officials have taken a keen interest in this topic, pushing for robust oversight of emissions. By contrast, countries like China have argued for looser scrutiny for developing nations.
