The thesis of this book, backed up by extensive research, is that the slight warming our Earth is undergoing now is part of a long-established cycle associated with activity on our sun, is not dangerous, and is not something we could do anything about even if there were any need to, which there isn't. If man-made greenhouse gasses are contributing to warming to anything more than the most trifling degree, the global warming activists have not come even close to demonstrating this.
This is more or less the train of thought that I've considered worthy of as much attention as that inconvenient truth. More on this next week when one of Al Gore's emissaries will give a presentation here in my neighborhood. An open mind is required, sure, but so is an open debate.
