PARIS (AP) — U.S. President-elect Joe Biden pledged Saturday to rejoin the Paris climate accord on the first day of his presidency, as world leaders staged a virtual gathering to celebrate the fifth anniversary of the international pact aimed at curbing global warming.

Heads of state and government from over 70 countries took part in the event — hosted by Britain, France, Italy, Chile and the United Nations — to announce greater efforts in cutting the greenhouse gas emissions that fuel global warming.
