Climate Talks Open in Madrid Amid Dire Warnings Lisa Bryant MADRID - Representatives of nearly 200 countries begin annual climate talks in Madrid Monday, shadowed by alarming evidence of a deepening climate crisis and the looming exit of the United States from a global pact to fight it. A pair of grim United Nations reports published in recent days underscore the scope and real-life impact of insufficient climate action -- underscored by global protests Friday in the latest show of people power. "Climate change is becoming real in ways people hadn't imagined earlier," said Simon Buckle, climate change head at the Paris-based Organization for Economic Cooperation and Development (OECD). "Maybe they were thinking the impacts would be a long way in the future. They're not; they're here." Presided over by Chile, which bowed out of hosting the meeting after social unrest at home, this latest meeting -- known by its acronym COP 25 -- aims to finalize rules for implementing the 2015 Paris climate pact. Environmentalists hope it will also set the stage for countries to beef up their greenhouse gas-cutting commitments at next year's conference in the Scottish city of Glasgow.
