As the air’s CO2 content continues to rise, nearly all of earth’s plants will exhibit increases in photosynthesis and biomass production; but climate alarmists periodically claim that elevated concentrations of atmospheric CO2 will lead to more droughty conditions in many parts of the world and thereby significantly reduce or totally negate these CO2-induced benefits. Therefore, to help determine to what degree this claim has any validity, we here review and summarize the results of numerous CO2-enrichment studies that were designed and conducted in such a way as to reveal the various means by which atmospheric CO2 enrichment may actually help a number of important food crops to successfully cope with this potential problem of more frequent periods of less-than-optimal water availability.
