Former Vice President Al Gore outlines a strong sense of reluctance on the part of the world powers to squarely face the facts about global warming. What was once an inconvenient truth can no longer be ignored, as Gore invokes the notion of the moral imperative - that the full recognition of a problem must compel action. This is not only applicable to world governments and multinational and corporate bodies, but must extend and unfold in individual behavior becoming more aware of our positioning within nature. Essential reading.
