Merchants of Doubt should finally put to rest the question of whether the science of climate change is settled. It is, and we ignore this message at our peril."-Elizabeth Kolbert "Brilliantly reported andwritten with brutal clarity."-Huffington Post"Merchants of Doubt" was one of the most talked-about climate change books of recent years, for reasons easy to understand: It tells the controversialstory of how a loose-knit group of high-level scientists and scientific advisers, with deep connections in politics and industry, ran effective campaigns to mislead the public and deny well-established scientific knowledge over four decades.
