If the acumilation of ice during an ice age reduces sea levells by hundreds of meters then is it poible that this may cause the earth srotational speed to increase and possibly wobble more?

Answer 1

There has been research that has found that a redistribution of water mass as a result of more or less ice would change things like rotational speed or wobble. The changes are very minor, however, and a person would never notice even if they did live 20,000 years through an ice age. Also, there are other things that can have the same result, such as the redistribution of air (this is known as the global wind oscillation).

Answer 2

The accumulation of ice during an ice age can cause a minor increase in Earth's rotational speed due to a redistribution of mass, but this effect is very small and won't significantly alter Earth's rotation or cause it to wobble more. The impact on the Earth's rotation from ice age changes is not substantial compared to other factors.
