The assumption of M. Milankovitch on the Earth albedo constancy in interglacial period was replaced with the alternative one. The model has been developed, where anomalies of the average annual temperature of the surface atmosphere were related with interannual albedo changes and thermal inertia of the hydrosphere. The surface temperature changes due to albedo actual and model changes were calculated.
