Abstract: Abstract Milankovitch theory—that climate is controlled by variations in the Earth's orbital parameters—has gained wide acceptance for its ability to account for two climate cycles: a 23-kyr cycle that is phase-locked to the precession-driven insolation cycle, and a 41-kyr cycle that is phase-locked to the obliquity-driven insolation cycle1–6. But, explaining the observed ∼100-kyr climate cycle in terms of Milankovitch theory—especially for the Late Pleistocene ice-age cycle—remains controversial in spite of a strong correlation with the ∼100-kyr cycle in the Earth's orbital eccentricity5. One problem is that eccentricity affects insolation mainly by modulating the precession cycle; its direct contribution to radiation change is too small (
