Model for the Assessment of Greenhouse-gas Induced Climate Change, and a Regional SCENario GENerator (MAGICC/SCENGEN ) uses emissions scenarios to predict global-mean temperature, sea level rise, and regional climate. Version 5.3 employs IPCC 4th Assessment Report (AR4) results. SCENGEN is a regionalization algorithm that downscales climate change information to a 2.5° latitude by 2.5° longitude grid. This tool can be used to: evaluate the consequences of different mitigation policies; assist the development of adaptation policies by highlighting areas of vulnerability; support the development of regional climate scenarios; inform users about the implications of various socioeconomic development pathways; and provide easy access to up-to-date data derived from AOGCM experiments.
