If you read past the bias in “ New row on climate ‘hockey stick’/a,” you’ll note that there are significant concerns about the validity of the models that show a dramatic increase in temperatures since 1900. Two points stood out. One: they were looking for a “hockey stick” pattern. Two: phenomena that we have fairly reliable historical records for, such as the unusual warm period from 800AD to 1400AD and the unusually cold period from 1600AD to 1850AD do not show up in the standard results. One of the controversial paper’s authors states that “uncertainties in the methods used for climatic reconstruction underestimate the changeability of climate in the past.” Hmmmm. Sound at all like there is a presupposition that only man can change the climate?/p
