UN climate summit opens in Turkey after year of extreme weather

World leaders, delegates, and climate activists are gathering in Antalya, Turkey, for the COP31 U.N. climate summit, which begins Monday amid a year of extreme weather and rising global temperatures. The summit, running Nov. 9-20, will focus on implementing previous climate pledges rather than setting new targets, with an "Action Agenda" including methane reduction and boosting renewable electricity from 21% to 35% by 2035. Delegates will also address financial aid for poorer nations adapting to climate change. The U.S., the world's second-largest polluter, will be absent under President Donald Trump, who withdrew from negotiations. The summit is jointly organized by Turkey and Australia, both criticized for coal reliance, and follows COP30 and COP29, which ended with little agreement on emissions cuts.
