The surface solar radiation over global and regional areas (including China) has obvious changed during the recent several decades. Before the middle or end of the 1980s, the surface solar radiation decreased (namely global dimming') and after that increased (namely global brightening'). The reasons for this change are multiplex and complex. The change of total cloudiness can not account for it reasonably while the change of aerosol may be important in some regions (including China). The change of surface solar radiation would have important climate effects. During global brightening', the warming effect of greenhouse gases would be more obvious. In this paper, the newest results in above three aspects are concluded and analyzed, which will be useful for climate change study in China.
