A new version of the Meteorological Research Institute Coupled GCM (MRICGCM2) is improved in reproducing mean climate of global-mean and meridional distribution of energy budget by mainly adjusting clouds representation. In the global warming experiments, the effective climate sensitivity is evaluated and found to increase more than 1K with the improved version of the model. Decrease of negative feedback due to cloud forcing can explain the most of the change in climate sensitivity.
