There isn't much doubt that Antarctica was in a different angle at one point, and a fertile land. The timing of when this occurred is questionable...but there isn't much doubt about this. But this tilt business is not an absolute thing...any number of earthquakes or meteors hitting the earth, can twist the angle slighly.

Just point into your mind a what-if situation. What if...four massive earthquakes occured within 24 hours and the tilt of the earth went south 2 degrees? The north pole would be nearer to Cold Lake, Canada...NY would be in the prevsious climate region of Montreal...Miami would move up on the climate location of North Florida and see more freezes. It doesn't take alot to make this scenario occur.

The earth spins like a top and the tilt changes like a top over VERY long time periods, I think the change may be as much as 5-7 degrees.

That would not happen. Think of the Earth as a giant gyroscope.

Note: Actually, the tilt of the Earth is oscillating back and forth slightly.

I just barely dabble in astronomy although it is an interest of mine. I like science in general although I gravitate towards the radio-electronics side being an amateur radio operator and so on. Still, I think a couple of my "kicks in the butt" towards this interest was the Moon landing of Apollo 11 when I was 3 and my grandmother being into things like astronomy, the ancient Egyptians and so on when she was a teenager in the 1920's. Back then, I remember she told me she had a book that documentated that the Earth's Axis tilt varied throughout history from something like 21.5 to 24.5 degrees and this is one of the reasons why climate changes and why the Sahara was a desert now as opposed to being a fertile area in the past. I wish she had that book until she passed on in 1997 and if she did, I would hope she would pass it to me, sounds like it would be interesting reading.
