“Taylor and Schlenker [not NASA scientists, but from Columbia University] found that an increase of 1 part per million of carbon dioxide raised corn yields by 0.5 percent, soybean yields by 0.6 percent, and wheat yields by 0.8 percent.
Put another way, yields may have increased 1–2 [percent] per year due to CO2 fertilization in recent years,” the authors wrote, noting the positive correlation between increased atmospheric carbon dioxide and greater agricultural yields in recent decades.
They also noted that the potentially dramatic fertilizing effect of atmospheric carbon dioxide might not be so unexpected, given how it’s used in actual agricultural greenhouses.
“The gas has long been pumped into greenhouses to spur photosynthesis and increase the yield of horticultural crops. Optimal CO2 concentrations of 900 [parts per million] have been suggested, which is over twice current ambient levels,” the authors wrote."
