Comments on J. J. Smulsky’s Paper 'A New Theory of the Earth Insolation Change over Millions of Years against Marine Isotope Stages'

Insolation calculations for solving the two-body problem have been analyzed. The errors associated with the simplification of the calculation algorithm of insolation and disregard (simultaneously) of the attraction of planets of the solar system and their satellites in calculations of the Earth’s irradiation have been indicated. The use of the method of equivalent latitudes in paleoclimatology has been shown to be inconsistent. The need to take into account changes in the meridional insolation gradient, which regulates the meridional heat transfer from the equator to polar regions, in paleoclimatology and paleogeography has been substantiated.
