1. Lots out studies out there, some running 10 or 20 years

This is a really clumsy summary of complex results (out the door in a second), but:

While plant growth in some studies did speed up under higher CO2 conditions, the growth spurts generally didn't last that long. When growth was goosed by CO2 plants, trees and shrubs grew faster, but in doing so, tended to use up soil nutrients faster as well, so that initial growth spurts leveled off after a few years.

In addition, some of the studies showed an advantage to grasses under high-CO2 conditions, and a relative disadvantage to trees and woody plants, which could indicate substantial shifts in the makeup of forest and grass cover in given habitats, especially given higher fire incidence and intensity, changes in temperature, rises in tree lines and things like that. I think you'll find this grass vs. tree study (with links) among recent posts on this board.
