Milankovitch cycles: eccentricity (~100,000 yr), obliquity/axial tilt (~41,000 yr), and precession (~23,000 yr, with a ~19,000 yr component) periodicities.
Of the three main Milankovitch cycles, the precession of the equinoxes (wobble of Earth's rotational axis) has a periodicity of about 23,000 years (composed of...
