You know, I appreciate the growing concern about the northern ice cap melting--the sea levels, the wildlife dying off--all those potentialities are alarming.
But isn't there another dire consequence? Imagine a top twirling--affixed to the top of said top is a thick heavy layer of dense material. Imagine what happens to that twirling top if that extra dense material at the top diminishes? Won't it wobble? Won't the entire skin of the earth (which floats on hot liquid) shift and fluctuate if the momentum of its rotation continues at speed but its polar density diminishes?
Is such a thing possible?
