The direct carbon dioxide effect on plants
Carbon dioxide may affect plants by changing the climate, but it can have another more subtle and quite separate influence, through its direct effects on plant physiology. Since CO2 is fundamental to photosynthesis, it makes sense that increasing the amount of CO2 in the atmosphere will tend to allow plants to photosynthesize faster. This then is one-half of the direct CO2 effect on plants. But there is also another less straightforward direct effect of CO2 on the water balance of plants. Why should this be?
