Nations at UN climate talks back universal emissions rules

(AP) After two weeks of bruising negotiations officials from almost 200 countries agreed Saturday on universal transparent rules that will govern efforts to cut emissions and curb global warming. The deal agreed upon at U.N. climate talks in Poland enables countries to put into action the principles in the 2015 Paris climate accord. But to the frustration of environmental activists and some countries who were urging more ambitious climate goals negotiators delayed decisions on two key issues until next year in an effort to get a deal on them. .
