Another death blow to the Hockey Stick: New paper finds many tree-ring analyses to be highly biased
New study calls for 'great caution in the interpretation of historical growth trends from tree-ring analyses.' The authors find that 'big tree selection bias' resulted in a fictitious 'doubling in growth rates over recent decades.' Consequently, tree-ring analyses claiming to link growth rates to historical temperatures would show a fictitious large 'hockey stick' increase in temperature over recent decades.
