Thanks for the link, but that site design is so mid-nineties it merits only a quick glance, and a quick and fruitless search for, e.g., the word 'methane' confirms the wisdom of moving on.

I can't think of a single person, let alone scientist, who denies that glaciation occurs in cycles governed by solar and planetary factors. I can think of somebody who aims to profit directly from a dubious collation of information. The guy flogging that book.

Well, "the guy flogging his book" sold one to me, and I read and thoroughly enjoyed it, and learned a few things about the author's branch of plate tectonics theory studies. I lent it to my dad, but it seems to have gone missing.

For the price, I'll probably buy another, and not just because I was intrigued by the scenario presented, but because I LOVE reading.

He also goes into magnetism and galaxial mechanics (albeit merely glancing off same) in a most unique manner in the book.

I'm not saying he's dead right, nor is he dead wrong, but he presents a series of compelling arguments for his theory, and is worth reading. He does sometimes seem to be preaching at times, mind you, but what author doesn't? < BG >.
