文摘

More interannual variability is expected for both aeration and drought stress. Decreased temperature stress in early spring cannot compensate increased summer heat damages. Future CO2 enhancement cannot compensate the risk of crop yield reduction. Precipitation and temperature change is the main driver to affect both low and high flows. The impact of CO2 on streamflow is only visible under very high flow conditions.
