Altogether, therefore, common sense suggests that with the plant productivity gains that result from the aerial fertilization effect of the ongoing rise in atmospheric CO2, plus its transpiration - reducing effect that boosts plant water use efficiency, along with its stress - alleviating effect that lessens the negative growth impacts of resource limitations and environmental constraints, the world's vegetation possesses an ideal set of abilities to reap a tremendous benefit from what the President inaccurately terms «carbon pollution» in the years and decades to come.
