Don't forget that life thrived during the Mesozoic era in spite of higher CO2 levels and temps than we have now. Not saying the climate isn't changing, just that the earth can take it far better than you seem to think.
Yeah, but humans (or current human civilization) simply can't exist with lethal temperatures and saturated CO2 levels. Even the mesizoic had more plant life than we have now, and that's being wiped out as we speak. Without land plants you can't have animal life, PERIOD. Anyone who thinks otherwise, or believes it wont be that bad, is under the payroll of the energy lobby. You can't have modern society if the wet bulb temperature is above lethal in half the world.
