Three slow changes in Earth's orbit — the stretch of its ellipse (eccentricity), the tilt of its axis (obliquity), and the wobble of that axis (precession) — combine to modulate summer sunlight at high latitudes. That insolation rhythm paces the glacial-interglacial cycles recorded in ice and ocean cores.

Eccentricity~100 kyr

Obliquity~41 kyr

Precession~23 kyr

Insolation forcing

Q = 0.50 e (t) + 1.0 ε (t) + 0.70 p (t)

Reading this result: With obliquity weighted highest, a ~41 kyr beat dominates — the pattern that paced glacial cycles before ~1 million years ago, when axial tilt led the forcing.
