I wish that were true. Unfortunately, adding CO2 to crops has a negative effect on nutritional yield. It can help in some circumstances, but mostly you just get a more dense, less nutritious plant. Plus, you get stronger weeds, which lowers yield as well.
And rising temperatures are really bad for crop yields in general.
