Mike Hulme, director of the Tyndall Centre for Climate Change Research at the University of East Anglia, thinks the reasons for the persistent differences lies in the complex ways we see and use climate change as a totem for other, deep-seeded ways in which we view the world. In his book Why We Disagree about Climate Change, Hulme calls climate a battleground between different philosophies of science, a justification for converting public commons into private assets, the inspiration for new social movements, and a threat to our security, justifying a new form of geo-diplomacy. This is not a "how to" book on fixing climate change or even a "best practice" book about ways some people think we could. Its "recipe", if we can call it that, is critical reflection, coming to understand how we think and why we disagree. That's not an observation that will help a director reach a decision about which action to take when, or how to report it. But if the solutions, such as they are, must be "clumsy", then route to them will probably lead us into disagreements. This book will help us understand better why we disagree.
