The U.S., Europe and a handful of other rich countries agreed to triple the financing they provide for climate-change projects in the developing world to at least $300 billion a year by 2035, signaling their commitment to the Paris climate accord despite a looming obstacle: the incoming presidency of Donald Trump.

Negotiators from nearly 200 nations made a nonbinding commitment that wealthy nations would aim to provide $300 billion annually by 2035 to help poorer nations.
