Planetary perturbations [mainly Jupiter’s] alter the orbital parameters of the Earth leading to different regions receiving different amounts of TSI ( Total Solar Irradiance  --  the flux of radiant energy per unit area ( normal to the direction of flow of radiant energy through a medium ) ).


Forty years ago, Hays, Imbrie, and Shackleton in a paper in Science tested the hypothesis that small changes in Earth's orbital geometry—namely precession, obliquity, and eccentricity — were responsible for the waxing and waning of the great continental ice sheets during the Quaternary period, which began about 2.58 million years ago . The paper is considered to be the “smoking gun” in support of the astronomical hypothesis of the Ice Ages, which is over a century old and most often ascribed to Milutin Milankovitch .
