Climate Change Impacts on Agricultural Yields

Projections of future crop yields are highly uncertain. At global to regional scale, CO2 fertilization has the potential to generally increase crop yields on current crop land. However, it is highly unlikely that yield increases due to CO2 fertilization will be fully achieved in most regions, as lon...
