Amazon.com: Customer reviews: Why We Disagree about Climate Change: Understanding Controversy, Inaction and Opportunity

"Having participated in the national and international debate over climate change for more than 15 years, I eagerly bought and read this book in the hope that it would examine the ideas and motives of both sides in the global warming debate. But that is not what this book is about.

The author, Mike Hulme, is a professor of climate change at the University of East Anglia, in the UK. He helped write the influential reports of the Intergovernmental Panel on Climate Change (IPCC) and many other government agencies that are commonly cited by alarmists in the debate. He has been one of the most prominent scientists declaring that "the debate is over" and that man-made global warming will be a catastrophe.

In this book, Hulme comes clean about the uncertain state of scientific knowledge about global warming, something alarmists almost never admit in public. For example, he writes, "the three questions examined above - What is causing climate change? By how much is warming likely to accelerate? What level of warming is dangerous? - represent just three of a number of contested or uncertain areas of knowledge about climate change." (p. 75)

Later he admits, "Uncertainty pervades scientific predictions about the future performance of global and regional climates. And uncertainties multiply when considering all the consequences that might follow from such changes in climate." (p. 83) On the subject of the IPCC's credibility, he admits it is "governed by a Bureau consisting of selected governmental representatives, thus ensuring that the Panel's work was clearly seen to be serving the needs of government and policy. The Panel was not to be a self-governing body of independent scientists." (p. 95)

All this is exactly what global warming "skeptics" have been saying for years. It is utterly damning to the alarmists' case to read these words in a book by one of their most prominent scientists.

How does Hulme justify hiding these truths from the general public? He calls climate change "a classic example of ... `post-normal science,'" and quoting Silvio Funtowicz and Jerry Ravetz, defines this as "the application of science to public issues where `facts are uncertain, values in dispute, stakes high and decisions urgent.'" Issues that are put into the category of "post-normal science" are no longer subject to the cardinal requirements of true science: skepticism, universalism, communalism, and disinterestedness."

In "post-normal science," consensus substitutes for true science.
