The Paris agreement is complex and works in a slow bureaucratic manner. It’s a mostly voluntary climate pact originally written in ways that would both try to reduce a worsening climate change problem and withstand the changing political winds in the United States.

Trump signed an executive order that begins the process of withdrawing from the Paris Climate Agreement, which he also did during his first term.

Various European leaders reacted to President Donald Trump's withdrawal from the Paris Agreement saying that they will stick to the landmark Paris climate agreement even though the United States has withdrawn from it.
