The possible response of global climate to the changes of background radiation derived from satellite measurement during 1983-2001 is analyzed. Estimation is made by means of one-dimensional energy-balance climatic model. It is shown that the increase of the global surface radiation by 3 W × m–2 through 1983-2001 should result in a corresponding rise of temperature, which exceeds the actual observed values by 0.6?C - 2.0?C. Possible causes of such disagreement are discussed.
