The Fifth Assessment Report of the Intergovernmental Panel on Climate Change, all 900 pages - will be officially tabled on Monday. Meanwhile, the key chapters and the Summary for Policy Makers were released on Friday.
In response, UN Secretary General Ban Ki-Moon said, "The heat is on. We must act."
US Secretary of State John Kerry said, "This is yet another wakeup call: Those who deny the science or choose excuses over action are playing with fire....the response must be all hands on deck. It's not about one country making a demand of another. It's the science itself, demanding action from all of us."
