On a different level, variations in axial tilt, in combination with other factors like axial precession and orbital variations, lead to complex cyclic interactions called Milankovitch cycles that are hypothesized to be the principal initiating factor for geologically modern ice ages, the roughly 100 Ky ice age cycles within the Quaternary glaciation.

Nice Wikipedia search. Unfortunately you don’t understand any of it.
