By saying "so what if its Non Linear" you reveal that you dont understand the implication.
Those that dont understand are afraid of the next doubling of CO2 concentration in the atmosphere. The scientific fact is that only a small increase in long wave absoption will result. ie the CO2 increase has only a small effect and not enough to do all of those horrible things predicted.
800ppm is fine! after all we have been to 7000 ppm plus and happily survived. Now how is that possible if there is that great tipping point that Al Gore and his mates preach about?
