is a 2009 book by English journalist and author Christopher Booker in which he asserts that global warming cannot be attributed to humans, and then alleges how the scientific opinion on climate change was formulated.

Booker concludes, "it begins to look very possible that the nightmare vision of our planet being doomed"[1] may be imaginary, and that, if so, "it will turn out to be one of the most expensive, destructive, and foolish mistakes the human race has ever made".

In the prologue, Booker claims that many people, including the former U.S President Barack Obama, were 'seriously misinformed' about the evidence surrounding Global Warming and the effects it might have on the world.

The book received a positive reception from non-scientists in the media: In The Spectator, Rodney Leach said it was one of the best of its type, remarking that Booker "narrates this story with the journalist's pace and eye for telling detail and the historian's forensic thoroughness which have made him a formidable opponent of humbug".

[12] Scientist Philip Ball, on the other hand, wrote in his review in The Observer that the book was "the definitive climate sceptics’ manual" in that it makes an uncritical presentation of "just about every criticism ever made of the majority scientific view" on global warming.

Ball also criticised Booker's tactic of introducing global warming deniers "with a little eulogy to their credentials, while their opponents receive only a perfunctory, if not disparaging, preamble".
