Climate Models and Forecasts The GCMs are used to assess past climatic trends and forecast future climate changes. The most sophisticated models couple atmosphere and ocean submodels and are known as Atmosphere–Ocean General Circulation Models (AOGCMs). Scientists can use GCMs to determine the relative effects of various climate forcing on temperature.
