In a move that should surprise nobody, President Trump today announced that the United States would withdraw from the 2015 Paris climate accord, an agreement between 195 countries to reduce worldwide greenhouse gas emissions. Trump did not provide details about the withdrawal, a process that according to the original agreement will legally take about four years. The president did proclaim that the U.S. would immediately cease implementation of the accord’s non-binding elements, including withdrawing from the U.N. Green Climate Fund, and offered to rejoin the accord or some future agreement under different, to-be-negotiated terms.
