#Dr. Nadine Brisson died during the study in 2011.

Crop simulation models are widely used to estimate the impact of climate change on crop yields. Such studies are often carried out with a single or small number of models in a limited number of environments without determining the uncertainty of the crop model impact estimates. The need for a coordinated effort bringing together multiple modelling teams has been recognized by the Agricultural Model Intercomparison and Improvement Project (AgMIP; www.agmip.org). AgMIP aims to provide more robust estimates of climate impacts on crop yields and agricultural trade, including estimates of associated uncertainties. Here, we present the AgMIP Wheat Pilot Study, the most comprehensive model intercomparison of the response of wheat (Triticum aestivum L.) to climate change to date, including 27 wheat models. Outcomes of the model intercomparison and implications for model improvement and climate change impact assessment are discussed.
