part of figure 11, the depiction of the Medieval Warm Period is inconsistent with the claim on page 128 that The Wolf minimum heralded the end of the Medieval Warming and the beginning of the 600 year Little Ice Age. It took only 23 years to change from a warm climate to a cool climate. In addition the 20th century temperature data have been falsified by showing the 2000 temperature as almost exactly the same is the peak circa 1940 rather then 0.6C higher.'" IPCC showed Mann's hockeystick in the beautiful "composite" curve which I linked. Look at it closely. They used a "baseline" of 1990 temperature anomaly = 0.0C. Plimer clearly states that his curve shows the same Mann data, but with a "baseline" of 1960-1990 average. This is roughly 0.3C cooler than the 1990 value, so the whole Plimer curve is slipped upward by this amount. Otherwise, it looks identical to me. The "spliced" part (labeled "global instrumental observations" in the IPCC composite) shows the early 20th century warming (around 0.5C on both curves), the mid-century cooling (around 0.2C on both curves) and the late 20th century warming (around 0.4C on both curves). Plimer shows 1998 to be at 0.5C; IPCC shows it to be at 0.2C. The difference is due to the different baseline of 0.3C. Simple arithmetic, J SMITH, not an "inconsistent" depiction. The model-based projection part (beyond 2000) has not been "spliced" onto Plimer's depiction (as it has in the IPCC version). This is pure
