> the fact that tree populations will evolve to adapt to increased CO2 Many climate models only aim to predict the next century or two because that's what's relevant for humans. Trees have long generation cycles and evolution tends to take many generations to show significant effects. So on geological timescales they will probably adapt, but considering the speed at which AGW is happening that adaption will be too late to be of interest.
