Empirical records provide incontestable evidence for the global rise in CO2 concentration in the earth's atmosphere. Plant growth can be stimulated by elevation of CO2; photosynthesis increases and economic yield is often enhanced. The application of more CO2 can result in less water use. Competition between crops and weeds could be altered. Increases in root biomass could also influence soil carbon storage and trace gas emissions. Having looked at the available data base, we will offer a series of priority targets for future research.
