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. 9% is in the ballpark, but I have not seen figure as high as 25%. following graph shows logarithmic nature of increases in temperature as result of increasing CO2 concentrations: 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. But the temperature increases, under scenarios of increases of CO2 are not big enough to make large scale displacement. Also, landmass gained for farming / plant growth potential (in Northern Hemisphere, Russia Canada) is higher than potential losses.
