MAGICC/SCENGEN is a user-friendly software package that takes emissions scenarios for greenhouse
gases, reactive gases, and sulfur dioxide as input and gives global-mean temperature, sea level
rise, and regional climate as output. MAGICC is a coupled gas-cycle/climate model. It has been used
in all IPCC reports to produce projections of future global-mean temperature and sea level change,
and the present version reproduces the results given in the IPCC Third Assessment Report (TAR).
MAGICC can be used to extend results given in the IPCC TAR to other emissions scenarios.
SCENGEN is a regionalization algorithm that uses a scaling method to produce climate and climate
change information on a 5° latitude by 5° longitude grid. The regional results are based on
results from 17 coupled atmosphere-ocean general circulation models (AOGCMs), which can be used
individually or in any user-defined combination.
