Acknowledgments This research was funded by grant number R 824996-01 from the Science to Achieve Results (STAR) Program of the U.S.E.P.A. The HadCM2 data was provided by the Climate Impacts LINK Project (DETR Contract EPG 1/1/68) on behalf of the Hadley Center and the United Kingdom Meteorological Office. The VEMAP data was obtained from the National Center for Atmospheric Research (NCAR), Boulder, Colorado.

Naming Conventions V = VEMAP, current conditions S = Sulfate, moderate climate change G = greenhouse gases, more extreme change 0.5X = half current climate variability 1.0X = current climate variability 2.0X = twice current climate variability

Conclusions Climate change will impact midwestern grain farmers, input suppliers, ag financial institutions Impacts will vary significantly within region, especially north to south Adaptation strategies include equipment improvements (working rates), later planting dates, varieties better suited to mid-season heat and climate variability, crop mix adjustments, changes in operation financing
Further research Where are the better-suited varieties? Will demand for better adapted crops make them worthwhile to grow? As time passes, models will improve – update research… Will ag policy keep pace with changes to the farming environment
