Nice try but the moon has more effect on the earth than the glaciers, and as the moon gets farther and farther away every year it is causing the earth to slow down.
The Moon causes ocean tides on Earth to bulge towards it. However, the Earth is rotating faster than the Moon orbits so the tidal bulge swings ahead of the Moons pull. The gravity of this off center bulge pulls the Moon to a higher orbit and in the process slows the Earth’s rotation a little.
Another consequence of the Moon being farther away is that it takes longer to orbit the Earth; the lunar month becomes longer. In the future, the maximum length of the day will be reached when the Earth rotates at the same speed that the Moon orbits. In other words, the day and the lunar month will have the exact same length, somewhere near 47 of our present 24-hour days. At this point, since the tidal bulge will not be swinging ahead of the Moon’s orbit, the Moon will no longer be moving away but will remain in a stable orbit.

So.... does that mean that women’s menstruation periods will occur every 47 days ?
