and fishing '(p 202). Figure 7.1 is about global temperature. A paper by Jones, Keith Briffa et al. noted that the schematic 7.1 (c) figure on p. 202 had no clear source, but can be traced to publications by Hubert Lamb representing the Central England temperature record; those publications have no explicit calibration against instrumental data, [and are] just Lamb’s qualitative judgement and interpretation of what he refers to as the ‘evidence’. Within the 1990 report, the LIA is taken to be global in extent but not the MWP. Climate over the last 1000 years is mentioned very briefly in the SPM of the 1990 report. The MWP is not mentioned at all, and the LIA described by "probably fluctuated by little more than 1°C. Some fluctuations lasted several centuries, including the LIA which ended in the [19th century] and which appears to have been global in extent". The MWP is mentioned in the executive summary to chapter 7, as "MWP around 1000 AD (which may not have been global)". 1992 supplement The 1992 report (appendix C) used only two graphs of pre-instrumental temperatures, from (Wang and Wang 1991). They show air temperature based on documentary evidence in East and North China from 1350 to 1950. Fluctuations are of the order of 0.5-0.75 °C and indicate, variably, colder-than-present temperatures before the 20th century. The graph stops in 1350 and does not show a MWP. The only text reference to the MWP is qualified by in this region in boldface. 1995 report (SAR) By 1995, research in the subject had advanced and hemispherical reconstructions of temperature were available, though only for the summer season (because tree rings are often most strongly influenced by summer temperatures). The 1995 IPCC report used a Northern Hemisphere summer temperature reconstruction (fig 3.20) from 1400 to 1979 by (Bradley and Jones 1993). This too shows no MWP (it only goes back to 1400) and colder temperatures otherwise before the 20th century, of the order of 0.5 °C colder. Fig 3.21 shows 8 ice core records from 1200 to present, which display a mixed pattern. The MWP and LIA are introduced, in the text, as "two periods which have received special attention... These have been interpreted, at times, as periods of global warmth and coolness, respectively. Recent studies have re-evaluated the interval commonly known as the Medieval Warm Period to assess the magnitude and geographical extent of
