versus other depictions of climate changes in Europe over the last thousand years. Believe we have discussed the upper graph and have agreed that this is identical to Fig. SPM-10b in The IPCC TAR Summary Report of 2001 with the noted exceptions. The lower graph purports to show climate change in Europe over the past 1,000 years. You quote Enting as criticizing this curve as follows: "In the lower 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." This is a "nit-pick", of course, but let's look at the provenance of Plimer's curve. Plimer does not give the specific reference for this curve, but it is a fairly close match to Fig. 7.1c in IPCC Climate Change 1995 (the second IPCC report), to which Plimer makes reference on p. 87. This curve (along with Mann's hockey stick) is also shown in Wiki: http://en.wikipedia.org/wiki/File:Ipcc7.\\... It shows that at the height of the MWP temperatures were around 0.4C higher than in the late 20th century, and at the coldest part of the LIA they were around 0.8C cooler. Beyond the mid 20th century, Plimer has added the three notable warming/cooling cycles of the 20th century (warming 1910-1945, cooling 1945-1975, warming 1975-2000), which IPCC did not show
