Some years ago it occurred to me that the polar ice caps help keep the Earth steady as it spins like a top while orbiting the sun.
One of the forces that keeps it from wobbling a lot is the presence of the two ice caps, which provide density and weight at the top and bottom of the planet.
If the polar ice caps begin to melt, I figured, the planet will start to wobble… maybe to the point of turning on its axis… like a top that falls down near the end of its spin.
Now science has found evidence that the process could be starting, thanks to global warming. The north and south poles have been drifting since 2006.
Could be the start of the long-prophesied Earth Changes… but might take centuries to happen.
Since writing this post, I stumbled upon a scientist’s prediction of melting polar caps, in which he uses detailed calculations and concludes that the Earth’s rotation (if not its tilt) would be minimal. His bottom line:
If the ice caps melt, changes in the earth’s rotation will be very far down on our list of concerns.
Here’s his website, for those interested:
