"Yes, but CO2 is a minor greenhouse contributor" Somewhere between 9% and 25%. Granted, it isn't the majority, but it does have an effect. Increasing its concentration can only increase it effect. "Don't know about dismal brown, but increased CO2 concentrations have already contributed to increased crop yields. " Not a surprise. And, as long as the climate stays the same, what you say is true. But many crops are not very heat tolerant, especially the high yielding ones.
