jrepka: Sorry I misquoted you on the precesion of the revovlution of the angle of Earth’s rotation. I just cited you because Dr. Fidelius doubted my numbers (which was a reasonable call). I thought the period was 22Kyrs, which with I think you concur. If it is, I’m glad I retained something from Astronomy 101. I understand that the angle of “wobble” varies. What caused the Ice Age may be a topic for a new thread. And, I’m not talking about the female response to Loverock during his teenage years. If he’s out of his teenage years or his alter ego is; I haven’t read the Loverock posts since Fri 7/16.
