I can back up all of these statements with references to scientific literature

We can just agree to disagree, since I consider that scientific literature to be agenda-driven crap. I grant that temperatures are rising. I grant that CO2 levels are rising. I laugh at the idea that humans are changing the global climate.

Fine with me, but I wonder why you would think that a 100 ppm increase in global atmospheric CO2 concentrations would have no significant effects at all.
