As various readers will know, Bishop Hill alias Andrew Montford has just published a book called The Hockey Stick Illusion. I recommend that people read it and post their comments here, so we can have an informed debate about the merits of the claims made in the book and about its main protagonists.
I have not finished reading it and will not write a review here. Two things stand out for me. One is the peculiar genre of the book which is a mixture of hagiography and detective story which is not always working well. While the style of the book is remarkably accessible to non specialists there are, at times, too many technicalities which are described in too much detail so that the lay reader (ignorant of the importnace of specific statistical methods) easily gets lost.
The more important aspect is the book's reconstruction of the paleoclimate controversy as initiated by Steve McIntyre in 2003. He is the main hero in the book; HvS and EZ also make appearances but are not given comparable attention. The story I take away from this book is the resistance of Michael Mann to have his original papers (MBH98 and MBH99) scrutinized by McItyre and others. It poses the immediate question of how these papers could have passed peer review initially when no one could replicate the results based on the initial information contained in the published papers (or based on later additionally material that was later released reluctantly). Instead, there was a counter attack calling McIntyre incompetent. This line of rhetoric seems to reappear at every turn of events, we have seen it in the emails, and we have seen it on this blog many times. This rhetoric can no longer be taken at face value by anyone who reads the book.
The Hockey Stick Illusion will require a refutation (based on an alternative reading of events or new facts) if such claims were to be substantiated.
