This is a simple IQ test anyone should be able to complete easily. Here are four images, which one of the images has elements that are not upside down? You have 5 seconds. Go.
Chances are, if you are not Dr. Michael Mann of Penn State University, you’d answer: “It’s a trick question, all of them are upside down”.
And you’d be right.
If you are Dr. Michael Mann, and continue to insist that data in the image (from Mann et al 2008 ) in the lower right is not upside down, please contact me about some real estate in Brooklyn I’d like to sell you at a bargain price.
As WUWT and Climate Audit readers know, Mann made some blatantly obvious mistakes in his use of proxy data in Mann et al 2008, where he claims to be able to make a present day “hockey stick” of climate without the use of Bristlecone Pines that he used in his flawed 1998 study which produced the original Hockey Stick. Mann inverted data, upside down if you will, notably the Tiljander sediment as pointed out by Steve McIntyre.
