The most conspicuous doubter in France is Claude Allegre, a former education minister and a physicist by profession. His new book, ``Ma Verite Sur la Planete'' (``My Truth About the Planet''), doesn't mince words.

He calls Gore a ``crook'' presiding over an eco-business that pumps out cash. As for Gore's French followers, the author likens them to religious zealots who, far from saving humanity, are endangering it. Driven by a Judeo-Christian guilt complex, he says, French greens paint worst-case scenarios and attribute little-understood cycles to human misbehavior.

He dismisses talk of renewable energies, such as wind or solar power, saying it would take a century for them to become a serious factor in meeting the world's energy demands.
