Perhaps I’m misinterpreting, but the article seems to claim Milanovitch cycles are based on eccentricity only instead of “ variations in eccentricity, axial tilt, and precession.” [0] That precession is more prominent seems to refine not repudiate Milanovitch.
A fun factlet is that precession is the artistic topic of a sculpture at the Hoover Dam:
While Polaris is our North Star, Hansen’s terrazzo floor points out that the North Star of the ancient Egyptians, as they built the great pyramids, was Thuban. And in about 12,000 years, our North Star will be Vega. [1]
