Query: Great Geology, Terrible Economics and Politics

The first third of the book does a great job of estimating carbon fuel production and consumption in the world. The book should have ended there and been published as a technical pamphlet (for which the author appears to qualified to discuss). The remainder of the book contains the authors non-scientific opinions about global warming, Middle Eastern politics and his obvious dislike of the United States. He implies that the world economy is dependent on carbon fuels, not because they are cheap and plentiful, but because the world was duped throughout the 20th century by large multi-national corporations. The author footnotes frequently, citing such notable sources as filmamker Michael Moore or New York Times op-ed pieces as if they were academic journal articles. All that the author says may be correct, but his credability falls short once he steps beyond the rocks.
