100,000-year rhythmicity of paleoclimate variations, that aroused in the Late Pleistocene, can be linked with corresponded long-term oscillations of insolation and seafloor volcanism, forced by gravitational forces in Solar system. This conclusion is based on wavelet analysis of variations of the earth’s orbit eccentricity, different paleoclimatic characteristics, and their known spectral estimates and seafloor volcanism data.
