Inconvenient truth in expanded detail is an apt description for this book. The book format can include a lot more information than a movie so if you want to know more about global warming than what is in Al Gore's movie, this is a good place to start. The author is from Australia so that country gets more coverage than one would otherwise expect. Nevertheless, the subject of global warming is well covered. The book was first published in 2001 and updated in 2006 so it may becoming a bit dated in a quickly expanding subject area.
