Here is the definitive expose of the distorted science behind the iconic global warming graph centrally responsible for the global panic about climate change.From Steve McIntyre's earliest attempts to reproduce Michael Mann's Hockey Stick graph, to the explosive publication of his work and the launch of a congressional inquiry, The Hockey Stick Illusion is a remarkable tale of scientific misconduct and amateur sleuthing. It explains the complex science of this most controversial of temperature reconstructions in layperson's language and lays bare the remarkable extent to which climatologists have been willing to break their own rules in order to defend climate science's most famous finding.The book also covers the recent leak of the email archives of the Climatic Research Unit which has led to the resignation of its Director, Professor Phil Jones, and exposed the degree to which climate scientists on both sides of the Atlantic have hidden and manipulated data to support their claims.
