This instantly ‘famous’ 2013 Science hockey stick paper derived from Marcott’s 2011 Ph.D thesis at Oregon State University, available here. His thesis doesn’t show a hockey stick ‘blade’ projecting above its anomaly baseline NCDC 1961-1990. H/T to Jean S, posted at Climate Audit. Something changed after the thesis was published to produce the new ‘blade’ in Science. That something was significant, since the Science paper’s Supplementary Information discussion said it did not enablediscriminating such a temperature variation (i.e. a‘blade’) on such a short a time scale.
