On the same day that the U.S. officially withdrew from the global pact to reduce emissions that cause climate change, presidential contender Joe Biden committed that he would rejoin the Paris Agreement if elected.

In a tweet late Wednesday, Biden wrote, “Today, the Trump Administration officially left the Paris Climate Agreement. And in exactly 77 days, a Biden Administration will rejoin it.”
