Every planetary scientist will tell you that Venus being slightly closer to the sun than the Earth is did not cause its runaway greenhouse effect. Something catastrophic happened to that planet, something that caused it to have a retrograde rotation about its axis that is slow in the extreme, something that melted the entire surface 500 million years ago, something that released virtually all of the CO2 on and in the planet into its atmosphere. Now, none of that has to do with the point I am trying to make. The point is that at some point, the concentration of CO2 in Venus' atmosphere made it not only uninhabitable by virtue of it becoming toxic to life, but at some point, the surface temperature simply became too hot to support life, or to support the ocean of water that is believed to have once existed there. There is no evidence that Venus started out this way. But it certainly is this way today. So my question is how much CO2 does it take for the greenhouse effect to become a runaway process on a planet like ours? How much CO2 are you willing to allow to be released into our atmosphere before you decide that enough is enough? And when you finally do come to that decision, will it be too late for our children, and their children?

You should post a graph of CO2 levels for all of Earth's history and then we can further discuss your awesome questions. Thanks!
That you believe that what CO2 levels were throughout Earth's geologic history are relevant to the CURRENT inhabitants of the planet only indicates the level of delusion to which you are willing to stoop to promote unethical and greedy corporate behaviors.
