Not impressed with the second study, either. Too many uncontrolled variables. A far, FAR better experiment would be to set up greenhouses, use the same species of plant, and experiment with different CO2 concentrations (such as 250PPm, 500, 750, 1000, and so on), and then compare densities from that.
Did you read the study? That's what they did, up to 500 ppm.
(d) Experimental: field trials
Solidago canadensis was grown in assemblages of prairie plants along a pre-industrial (subambient) to projected Ca gradient (500 ppm) in the Lysimeter CO2 Gradient (LYCOG) facility located in central Texas USA.
Are you even trying?
I'm not trying to argue that increasing co2 is inherently bad or catastrophic.. I just think we need to be reasonable about the potential ramifications and respond accordingly.
