Hi Richard, H2O is one of the most powerful greenhouse gases and typically exists in the atmosphere at 10 times the concentrations of CO2 or methane. Extensive man-made irrigation systems added to man-made expanses of commercial crops and grazing fields have increased day-time ground temperature, adding more moisture to the atmosphere and causing at least 3 times more warming than CO2 or methane.

That's fascinating, thank you.
