Orbital theory climate
WebJun 5, 2024 · The theory that orbital cycles could influence climate was first put forward by Serbian mathematician Milutin Milanković in the early twentieth century. He calculated … WebVariations in the climate of the Sahara region can, at the simplest level, be attributed to the changes in insolation because of slow shifts in Earth's orbital parameters. The parameters include the precession of the equinoxes , obliquity , and eccentricity as put forth by the Milankovitch theory . [2]
