ABSTRACT
Assessing the impact of climate change on crops requires an overview of the various aspects of climate that are projected to change and an evaluation of the individual and combined effects of these changes. Uncertainty in our understanding of the impacts of climate change on crop production arises from our uncertainty about change in the climate itself and also from uncertainty in translating those changes into changes in crop production. In this chapter, we provide an overview of our ability to simulate future scenario climates at regional scales with a particular eye toward the climate needs for crop modeling.
