equivalent levels of greenhouse gasses, which includes potent greenhouse gasses like methane and nitrous oxide, would bring up the carbon dioxide equivalent levels to around 450 parts per million. it's increasing at an increasing rate. if we go to 560 part per million, a doubling, the change in temperature would be 11%. scary enough for a doubling. we consider a stabilization of 560 parts per million along with a lot of other people as being on he optimistic side. nobody knows camp be technological breakthroughs or 0 might not. the international energy association project its most likely stabilization to be around 700 parts per million. so it's predicting that we will good to 700 parts per million below turning down the stop. a difference between a stop in the flow in order to get the stock down it's not enough to stabilize the flow. you have to calls the flow to be decreasing. that's a little known but very important point to get a doubling would require us to lower our emissions quite considerably. okay. so figure two then, gives the change in temperature probability distribution for carbon
