A major UN climate conference formally opened Monday in the Peruvian capital, with delegates intent on finalizing a new worldwide agreement on global warming. For 12 days, representatives of 195 countries are to debate at the UN Framework Convention on Climate Change (COP-20) conference, working towards a climate agreement for signing in Paris in late 2015, dpa reported. The main goal of the conference is to reach a compromise on reducing emissions of greenhouse gases in order to limit global warming to a maximum of two degrees Celsius. Ahead of the gathering, Peruvian President Ollanta Humala asked the international community to build "the largest alliance in history for the sake of the climate and of development." -- SPA 20:47 LOCAL TIME 17:47 GMT تغريد
