Impacts on Agriculture
qBased on experimental research, crop yield responses to climate change vary widely, depending upon species and
cultivar; soil properties;
pests, and pathogens; the direct effects of carbon dioxide (CO2) on
plants; and interactions between CO2, air temperature, water
stress, mineral nutrition, air quality, and adaptive responses.
qEven though increased CO2
concentration can stimulate crop growth
and yield, that
benefit may not always overcome the adverse effects of excessive heat and drought.
