The wobble in Mars rotation caused major ice ages every 120,000 years. How does earth compare?

Question

Is earth's wobble the cause of ice ages here?

Answer 1

Venus wobbled so much that its axis of rotation is upside down. It is caused by tidal effects from the Sun.

Mars has wobbled so much that it has had very high inclinations (and inclination close to zero) many times in the past.

Mercury does not wobble because it is in a tidal harmonic spin mode.

Earth wobbles very little because the Moon, being very big compared to Earth, provides stability (the tidal effect of the Moon is greater than that of the sun).

In comparison, Mars has puny satellites (Phobos and Deimos are tiny little things compared to our Moon -- your rule, Moon!).

Still, the tiny wobbles of Earth's inclination does contribute to making ice ages longer or shorter.

Answer 2

It depends on what you you mean by the "next ice age." If you were to define the next ice age as beginning when the Earth starts to cool, then it is 6,000 years old. If you define it by how long it will take glaciation to reach its maximum extent, the answer is 100 thousand years. The current global warming will not delay the next ice age by more than a few centuries, because the methane will be oxidized and the excess CO2 will be absorbed by the oceans and, if there is enough precipitation, by plants, but do not be concerned, because glaciation is an extremely slow process. In addition, most of the world is still warm even during ice ages and falling sea levels would enable crops to be grown on the continental shelf.

Answer 3

The Moon stablizes Earths rotation, wobbles are minor.

Answer 4

We have better cars.
