If the polar ice caps of earth were to melt, the oceans would be deeper. strictly speaking, what effect would this have on earth's rotation?

The effect that the rise in sea level would need would be the slowing down of the Earth in its rotational movement.

For several years, humans have been concerned with establishing a universal measure of time for the entire Earth. However, some natural phenomena have caused time to slow down, affecting the rotational motion of the Earth.

One of the studies that focuses on this phenomenon is the Munk riddle, which compiles a series of facts related to the ocean such as tides and rising sea levels to establish that time has slowed down due to these phenomena.

Taking this research as starting point, other researchers have established that the Earth's rotation has been affected by the rise in sea level because this moves it away from the moon by modifying the measurement of time.
