The Climate Subsystem in IMAGE Updated to MAGICC 6.0

by M. Schaeffer and E. Stehfest

- Tecnical background report on the upgrade of the simple climate model MAGICC within the IMAGE model ("Integrated Model to Assess the Global Environment") of PBL. This report presents details about the improvements and the re-calibration of the model, it shows the model results and discusses the similarities and differences with the previous IMAGE versions and the new MAGICC 6.0 version. The single most important advantage of the new IMAGE model is that, in combination with MAGICC 6.0, the model can reproduce the time-dependent response of AOGCMs for various scenarios, by adjusting the values of a limited number of parameters. This makes the IMAGE model better suited to provide plausible projections of future climate-change feedbacks and impacts.
