Orbital tuning — refers to the process of adjusting the time scale of a geologic or climate record so that the observed fluctuations correspond to the Milankovitch cycles in the Earth s orbital motion. Because changes in the Earth s orbit affect the amount and… … Wikipedia
100,000-year problem — The 100,000 year problem is a discrepancy between past temperatures and the amount of incoming solar radiation, or insolation, which grows and shrinks periodically on a 100,000 year (100 ka) timescale.Due to variations in the Earth s orbit, the… … Wikipedia
