New paper finds tree-ring proxy temperature data is ‘seriously compromised’ — Published in Climate of the Past
'More bad news for Michael Mann: A new paper published in Climate of the Pastfinds that 'modern sample bias' has "seriously compromised" tree-ring temperature reconstructions, producing an "artificial positive signal [e.g. 'hockey stick'] in the final chronology." Needless to say, Mann's hockey sticks are also seriously compromised by statistical techniques that produce hockey sticks from random numbers, use of upside-down data, the trick to hide the decline, the most important tree in the world, use of bristlecone pines which were condemned by the NAS for use as temperature proxies, and a complete lack of validation sk
