False premise. CO2 is reactionary, an effect, not a driver. Discredits the rest.
Yes, resting too heavily on that, not qualifying it, does discredit all of the rest. Any sane debater knows that. Only someone who considers themselves to be spouting holy writ does not.
There is ample data that CO2 causes warming. But, within the earth’s system the impact levels off at 400ppm. Plus, if you push the level up to 1200ppm the food crops go bananas. Double, triple harvests. This has been tested in greenhouses.
