I can't believe some of the stupid shit I hear on this board for allegedly being about science.

CO2 is not remotely a significant bottleneck for plant growth. Plants are starved for nitrates and phosphates far more than for CO2, which is why we bombard them with fertilizer, not CO2. There is far more CO2 in the atmosphere than plants could ever use.

>Available data suggest that plants do not fully realize the potential increases in productivity associated with increased atmospheric CO2
