The Paris climate accord should be the starting point for nations fighting global warming, not the finish line, United Nations Secretary-General Ban Ki-moon said at a signing ceremony for the landmark agreement.
Ban challenged leaders from 171 nations gathered at United Nations headquarters Friday to move beyond promises of the accord brokered in December and undertake steps to reduce pollution and slow warming linked to rising seas, heat waves and droughts.
