Climate change will impact horticultural production in the future. The present work assesses the future climatic impact on regional horticultural production by establishing a basic frame of a climate impact modeling chain. Using high resolved simulated climate time series of future alternatives of the worlds development, long-term trends of various climate effects were assessed. For this purpose, simulated climate time series were calibrated and effects of resolution, bias, bias correction, scenario, climate model and impact model as well uncertainty propagation along the simulation chain...
