Hi Ahmed
Access to the base of these models is not possible. You can use the output of these models based on different scenarios of CO2 concentration on the basis of human activities. The outputs of each GCM model are presented in the website of that model (find by search the name of model), and also in some of other sites like the web site of IPCC.
Good Luck.
