Nicaragua has decided to join the Paris climate accord, and President Daniel Ortega has told state media that his government will “soon” sign on to the landmark agreement. Ortega initially refused to join the deal in 2015, claiming it did not mandate enough sacrifices from wealthier countries. It isn’t yet clear what changed Ortega’s mind. In any case, that leaves the U.S. and Syria as the only two nations that have refused to support the agreement to combat global warming. President Donald Trump has said it creates too many restrictions on U.S. companies.
