Question
QUESTION: I read in a science book that the earths wobbles like a spinning top that takes 26,000 years to complete a full wobble. We call this " precession". The book goes on to say that the earth's axis changes enough so that in 13,000 years, the north star will be Vega instead of the current Polaris. What is the amount of the wobble and wouldn't this cause some big climate changes?

ANSWER: The amount of this precessional wobble is significant, and is enough to cause significant change in the climate.  As a matter of fact, the Sun's energy output and this wobble are the MAIN cause of climate change.  Forget about all of the garbage you hear about Global Warming due to Man and Carbon Dioxide. That is a  unch of nonsence, especially since Carbon Dioxide is NOT the main greenhouse gas.  For more info on this, go to a section on my web site t:

QUESTION: Thank you. I read your article and learned a bunch. I now have much more supporting evidence to back up my belief that we are being conned by the media and politicians. Just curious, what is the degree change of the earth's axis from the wobble? Wouldn't that wobble  change the location on the tropics and the arctic circles?

Answer
As we are now tilted 23.5 degrees, at some point we will be "straight" up and down, tilting at zero degrees, then being tilted 23.5 degrees the other way.  The result around 12000 years from non, is that we WILL be closer to the Sun in the summer.  Much MORE hotter climate.  YES, the climate all over would be changed drastically, not only in the teopics.
