UN climate talks in Poland have ended with delegates reaching a compromise on how to fight global warming. After 30 hours of deadlock, they approved a pathway to a new global climate treaty in Paris in 2015. The agreement was achieved after a series of last minute compromises often involving single words in draft texts.
Several major environmental groups, including Greenpeace and WWF, have walked out of UN climate talks in Warsaw, Poland in protest at what they see as a lack of progress towards an international deal to curb rising global greenhouse gas emissions.
