"A splendid and important book. The public needs better guidance in interpreting what is heard in media reports about climate change and this book is enormously helpful in this regard, and will be widely referred to as the issue unfolds over the next five years." William Leiss, author of In the Chamber of Risks: Understanding Risk Controversies. "Haller has an important contribution to make. He is clear, persuasive, and does a good job at bringing together different strains of thinking in environmental decision making. His book is extremely timely and environmentalists are in dire need of guidance when it comes to decision making in the face of scientific uncertainty."
