Well you have to admit, both the magnetic reversals and precession have roughly the same period. One must suspect a causal link. I would disagree. Orbital characteristics, including precession, are well understood phenomena that are not chaotic over the short term of years we're dealing with here. The magnetic field, however, is based on the dynamic flow of metallic fluids in the interior of the spinning Earth, and the complex nature of the process makes it very chaotic and difficult to predict. As to the two effects having similar time frames, that seems to not be true. The magnetic reversal last happened about 780,000 years ago and the record looks very random to me, with intervals much shorter and longer visible from the historical record. I've just located a book in my library with much good info on these topics: "Paleoclimatology: Reconstructing Climates of the Quaternary -- Second Edition" by Raymond S. Bradley, copyright 1999 Academic Press, International Geophysics Series Volume 68. I would caution you; you would be less impressed by the "Global Warming" scare after reading this. Our planet's demonstrated resilience and climatic stabilization is very impressive. By the way, the Neutrino Report is absolute, utter hogwash. Do you want a point-by-point rebuttal, or is "Bullshit!" an adequate commentary? The other site looks good, and seems to be a reasonable treatment of the material.Considering modern man has been around for over 20,000 years we seem to have come an awfully long way in just the last 2,000 years. Indeed, and it's particularly impressive looking from our end of the scale. In a similar fashion, life got going nearly 4 billion years ago, but it has only been in the last 15% of that time frame that cells got together and cooperated to form multi-celled creatures. Once that happened, evolution has moved at an explosive rate. It's amazing what people have accomplished in the last few decades. Now, if we could live up to our potential... Level Head
