Last, best hope:’ Leaders launch crucial UN climate summit

A crucial U.N. climate summit opened Sunday amid papal appeals for prayers and activists’ demands for action, kicking off two weeks of intense diplomatic negotiations by almost 200 countries aimed at slowing intensifying global warming and adapting to the climate damage already underway.

As U.N. officials gaveled the climate summit to its formal opening in Glasgow, the heads of the world’s leading economies at the close of their own separate talks in Italy made pledges including stopping international financing of dirty-burning coal-fired power plants by next year. But much of the agreement was vague and not the major push some had been hoping for to give momentum to the climate summit.
