The consensus among publishing scientists on global warming is widely said to be “97%.” But that is false. If it were true, to find a single peer-reviewed article that rejects anthropogenic global warming, you would need to read, on average, 33.3 articles. Instead, you need to read nearly 5,000. The consensus among publishing scientists exceeds 99.9%. (See here.)

Scientists have been wrong before (think of continental drift). Could they be wrong today about global warming? Of those who doubt that humans are causing global warming, 40% believe scientists are engaged in a conspiracy. Could the conspiracy theorists be right?

“James Lawrence Powell breaks new ground. His scholarship is deep, and his stories are well-written and enriched with human detail. Anyone with an interest in how science progresses will profit from reading this book.” —Spencer Weart, author of THE DISCOVERY OF GLOBAL WARMING

“Deep time, continental drift, meteorite impact and climate change: each of these twentieth-century geoscientific discoveries was once viewed as heretical. So reminds geologist James Powell in this exemplary treatise on scientific progress. He traces the evolution of each landmark finding through the work of the dogged researchers who proved it, step by step. Many fights were hard-won, as shown in the efforts of Gene Shoemaker, Luis and Walter Alvarez, Robin Canup and others who established connections between meteorite impact, the birth of the Moon and the extinction of the dinosaurs.” —Nature.

“A compelling narrative of the ideas and personalities that shaped these big questions over the past two centuries. This is first-rate story-telling, with heroes, villains, and the often-unexpected discoveries that created revolutions in our concept of our planet.”—David Morrison, Skeptical Inquirer

“Scientists come off as fallible and stubborn as anyone, and indeed Powell says that ‘in science, being wrong is inevitable and indispensable.’ But he makes it clear that the process of science eventually succeeds in producing the best explanation of available data. In the case of anthropogenic global warming, there is no dispute in the scientific community and, despite media claims, this is borne out by peer-reviewed articles (of which only one in a thousand claims that this is not the case). Powell concludes that Big Oil is doing exactly what Big Tobacco did in trying to obscure the truth for its own ends.”—Publisher’s Weekly
