We have seen that carbon dioxide aerial fertilization can decrease the future size of deserts....
The Amazon rainforest is less vulnerable to die off because of global warming than widely believed because the greenhouse gas carbon dioxide also acts as an airborne fertilizer


Speaking of aerial fertilization, Vanuytrecht et al. conducted a survey of literature results of field experiments with elevated CO2 on commercial crop plants. They looked at wheat, barley, rice, soybeans, potatoes, sugar beets, cotton, corn, sorghum and ryegrass (used for hay).

On average for a 200ppm increase there was a 15% increase in above-ground biomass and yield, with a 25% increase in root mass. Water use decreased by 5%, resulting in a greater gains in 'water productivity'.
