Technically speaking, warming world means it has been colder so you are basing your argument on a previous temperature which who's to say is correct. We are part of the carbon cycle, whos to say what we are doing is wrong, mother nature may be using us to feed the plants to green the place up. Personally the thought of living in a cold desert is not appealing and taxing, maybe trading, plant food, co2 the basis of all life on earth by predatory religous sychopaths even less.
