Crop yields have been on a century long increase (we produce about 5x more corn per acre than 100 years ago) in part due to CO2 fertilization, in part due to improvements in technology:

You'll notice from the charts year to year variability happens (droughts, heat waves, freezes, etc) but the long term trend is up and to the right.
- ratboy666 4y agoThank you. And... as a note. The following statement has been down-modded in the past (this is truly an "uncomfortable truth"): If we go with no-CO2/no fossil fuel policy, we will reduce farming production, leading to famine and the likely death of (many) people. Of interest is that solar, wind, geothermal and nuclear cannot help.
