Extended Data Figure 6: Centennial temperature proxy anomalies updated from ref.15.
From: Northern Hemisphere hydroclimate variability over the past twelve centuries
a, Gridded, weighted, centennial proxy anomalies values derived from the data listed in Supplementary Table 2 and shown in Fig. 1b. Anomalies are shown relative to the centennial mean and standard deviation over the eleventh–nineteenth centuries. The colour scale is truncated at −2 and 2 and areas with insufficient proxy coverage to compute a gridded weighted mean value are left white. b, Gridded, weighted, centennial anomalies for simulated median values of annual mean temperature from six atmosphere–ocean coupled general circulation models. Only values from the same grid cells that are covered by proxy records are extracted (Methods).
