the original global temperature schematic which appeared in the ipcc first assessment report and seemed to show the medieval warm period (mwp) hotter than present was based on the central england temperature record, and ended in the 1950s.

this graph extended the similar graph in figure 3.20 from the ipcc second assessment report of 1995, and differed from a schematic in the first assessment report that lacked temperature units, but appeared to depict larger global temperature variations over the past 1000 years, and higher temperatures during the medieval warm period than the mid 20th century.
