UN climate talks begin as global temperatures break records
One key agreement that will have to be made at the currently ongoing UN Climate Change Conference in Lima which takes place from 1-12 December is the scale of "intended nationally determined contributions" (INDC), writes Matt McGrath, Environment correspondent for BBC News.
By the end of March next year, all countries are expected to announce the level of their efforts to cut carbon as part of the Paris deal.
"Developed countries want a narrow scope for those guidelines, but developing countries are pushing for finance and adaption in them," said Liz Gallagher from the think-tank E3G, and a long-time observer of the UN talks process.
"That seems to be a tactical move to make sure that finance and adaptation get more political attention than in the past - for me that's where the big tensions in Lima will be."
