Reducing CO2 levels too far might be a bad idea - some greenhouse effect is a necessary criterion of there being any life on Earth at all - but that's not an argument against trying to keep them in the 300-450ppm range.
It's also the case, though, that we're emitting CO2 at a rate that would be impossible to counterbalance by reforestation, and that global warming (in the short term, at least) is likely to cause more plant deaths than growth owing to increased forest fires and so on.
Beyond that, cheers for pointing out the blindingly obvious.
Right: home time!
I think you're right that a space mirror would be a daft way to solve the problem, btw.
