SHARM EL-SHEIKH, Egypt — "Cooperate or perish," the United Nations chief told dozens of leaders gathered Monday for international climate talks, warning them that the world is "on a highway to climate hell" and urging the two biggest polluting countries, China and the United States, to work together to avert it.
This year's annual U.N. climate conference, known as COP27, comes as leaders and experts have raised increasing alarm that time is running out to avert catastrophic rises in temperature. But the fire and brimstone warnings may not quite have the effect as they have had in past meetings because of multiple other challenges of the moment pulling leaders' attention — from midterm elections in the U.S. to the Russia-Ukraine war.
