Unfortunately, reality differs from your opinion. Plants that use C3 photosynthesis (which include virtually all food crops except corn & sugarcane) are most efficient at around 75-80 degrees. Their efficiency drops off rapidly above 100F, and the process pretty much shuts down above 115F.

Ever stop to wonder why the real 'grain belts' of the world are in the middle latitudes, and not the tropics?
