The third (c) schematic was labeled, "the last thousand years" with a dashed line that "nominally represents conditions near the beginning of the twentieth century." The graph is below. IPCC-FAR 1990, Figure 7.1c "Schematic diagram of temperature variations over the last thousand years. The dotted line nominally represents conditions near the beginning of the twentieth century." I think it may be fair to say that the biggest mistake the IPCC has ever made was using the word "global" with reference to the (c) schematic, because that objectively is not the case. It was a replica of Hubert Lamb's reconstruction of Central England temperature (CET), where Central England is ...
