Sensitivity Experiments as Simulated with an Energy Balance Model

Changes of the global temperature induced by the changes ice and snow areas, solar constant, surface albedo, carbon dioxide and aerosol have been simulated with a one–dimensional energy balance model. The effects of several factors on the ice age temperature have been analysed. Possible numerical results of the global temperature change induced by the natural variations and human activities are shown. Therefore, some reference values are given to protection of the atmosphere and environments
