Regular wobbles in the Earth's tilt were responsible for the global warming episodes that interspersed prehistoric ice ages, according to new evidence. ... Drysdale and colleagues suggest that the Earth emerges from ice ages due in large part to changes in the tilt of the planet in relation to the sun, otherwise known as...

Superimposed is a subtler wobble. The axis keeps steady in space, but over an uneven period of about one year, the bulk of the earth moves slightly in relation to the axis.

Chandler wobble - Wikipedia, the free encyclopedia
The Chandler wobble is a small motion in the Earth's axis of rotation relative to the Earth's surface, which was discovered by American astronomer Seth Carlo Chandler in 1891. It amounts to 0.7 arcs...

The magnetic poles are different from geographic poles, the surface points marking the axis of Earth's rotation. Magnetic poles are known to migrate and, occasionally, swap places. ... The Earth's Wobble has a 7 year cycle which produces two extremes, a small spiraling wobble circle and a large spiraling wobble circle,

The Wobble of Earth's Axis; The third orbital change that Milankovich studied is called precession, the cyclical wobble of Earth's axis in a circle. The motion is like a spinning top when it is about to fall over. ... By itself, the wobble of Earth's axis does not directly cause temperature changes like orbital shape and tilt.
