The Paris text proposes the following:
• To peak greenhouse gas emissions as soon as possible and achieve a balance between sources and sinks of greenhouse gases in the second half of this century
• To keep global temperature increase well below 2C (3.6F) and to pursue efforts to limit it to 1.5C
• To review progress every five years
• $100 billion a year in climate finance for developing countries by 2020, with a commitment to further finance in the future.

Key disagreements But Oxfam said the deal is set to short-change the world's poorest and most vulnerable people.
Martin Kaiser of Greenpeace, speaking before the text was released, said there had been disagreements over how and when to phase out fossil fuels and issues such as financing. Executive Director Helen Szoke said: "Only the vague promise of a new future climate funding target has been made, while the deal does not force countries to cut emissions fast enough to forestall a climate change catastrophe."
"There's been a lot of discussion whether the long-term goal will give a clear signal to phase out fossil by mid-century or is there a risk that it will be much later?" he said.
"There have been also a lot of arguments about the financing package because it was quite clear that for the US and for Europe it's such a big step forward which is hardly to believe they will do it.
"So everything seems to be sorted but we don`t know yet whether it's a good one or a bad one."
