WebJan 16, 2024 · The Earth's eccentricity occurs in a cycle that has been well documented. Climatologists refer to this cycle as periodicity. The periodicity is 100,000 years—that is, the time necessary to change the orbit from a nearly circular one to a more elongated one. The 100,000-year problem (also 100 ky problem or 100 ka problem) of the Milankovitch theory of orbital forcing refers to a discrepancy between the reconstructed geologic temperature record and the reconstructed amount of incoming solar radiation, or insolation over the past 800,000 years. Due to variations in the Earth's orbit, the amount of insolation varies with periods of a…

How Variations in Earth’s Orbit Triggered the Ice Ages

WebAug 5, 1997 · Three strong peaks are present in the eccentricity spectrum: near 0.0025 cycles per kyr (400-kyr period), near 0.08 cycles per kyr (125-kyr period), and near 0.0105 cycles per kyr (95-kyr period). The disagreement between the spectrum of climate and that of eccentricity is evident. porsche profil
