Yes, but not faster than the total mass of crops drops due to the increase in heat. Crop yield per plant in a controlled environment where only CO2 is increased != total crop yield given all of the circumstances involved in climate change.
CO2 as a heat trap is the problem, not so much CO2 in the atmosphere as an input to plant and animal life.
