This session calls for contributions addressing a wide range of scientific issues related to preparation and applications of climate change projections. Presentations related to issues such as choice of emission scenarios, ensemble generation, model drift, model evaluation and skill testing, model output calibration and bias correction, statistical and dynamical downscalling of climate change projections, preparation of climate change scenarios and description of practical issues related to applications of climate information to decision making and biophysical modeling are invited. In addition contributions describing the new CMIP5 climate change simulations, and results from analysis of CMIP3 and other modelling and process studies are also welcome.
