I listened to your first link but have to get to sleep really early tonight. (Personal information warning: my wife is having minor surgery at eight AM tomorrow and I want to be there.) I'll listen to the other two tomorrow.

I want to emphasize that I'm a layman so if anyone wants to weigh in on this, please do.

The eleven-year sunspot cycle is a very real, well-known pattern. In junior high, I got an amateur radio license and it was a couple of years before the peak of the cycle. You could easily see the sunspots using a telescope with the right filter. Then the shortwave radio frequencies were alive with activity and even with a ninety-watt transmitter I contacted other amateurs in Australia, Africa, and Europe regularly. Now we have the Internet so there are fewer shortwave broadcasts but I still have a shortwave radio—not the ham license anymore—and it is easy to tell that we are near the eleven-year minimum of the cycle. Davidson is exactly right about that.

Who is Davidson? I don't know but he's not an academic or he would say so. Being an academic is a kind of double-edged sword. You have qualifications but you had better watch what you say or you will lose that nice job you have. If you make claims outside those generally accepted in your field, it gets risky. For example "Egyptologists" insist that the Great Pyramid and the Sphinx are about 3,500 years old but a well-read layman knows they are considerably older. We already talked about Gobleki Tepe that was built about 13,000 BP. Academia is very conservative. So in Davidson's case, his not being an academic cuts both ways: he is freer to make claims but is he really qualified? He sounds like it but I can't be sure on a lot of his points.

I agree with him that so-called global warming and the greenhouse effect are just not true and if you search for it you'll find some Nobel Prize winners who come out and say just that. Usually, they are older academics near the end of their careers and have nothing to lose. Some of them say we're entering a minor ice age as Davidson does.

Polar drift and shifts: People way more qualified than me have been talking about this for a long time. There is a lot of evidence that Antarctica was at one time sub-tropical.

He talks about the Bermuda Triangle that we've all heard of but I dismissed that a long time ago however I could be wrong. Lots of ships and some planes have disappeared in that area but it is one of the busiest areas in the world for shipping and air traffic. I'm open to proof that it is a fact but frankly I doubt it. He also mentions the Dragon's Triangle in Asia but I have never even heard of that after living over half my life in Asia. But I need to look at his websites before deciding on this.

Global cooling caused by volcanic dust clouds: If you've heard of Krakatoa, the massive eruption that happened in 1883, then you probably know it caused global cooling for at least two years worldwide. Davidson mentions the same area—between Java and Sumatra— but doesn't mention Krakatoa, maybe because of time constraints.

To be honest, I'm not sure if he is for real or trying to sell books. More research is needed, for me I mean.

Speculation: What if a few governments around the world knew what Davidson is saying is right and some cataclysm is just around the corner? Would they tell us ordinary people? I doubt it. Have you heard of Deep Underground Military Bases (DUMBs)? Some good evidence suggests that they are real, but are they to protect the lucky few in the event of a nuclear war or in the event of the polar shift Davidson is talking about? Damned if I know.

Tomorrow I will listen to the other two and probably give you shorter answers than this one.

Nice talking to you Tom.
