For the record, in the case of this «divergence», after dropping that post 1960 portion, the comparison between the reconstruction and the temperature record was done using decadal «smoothing» (basically weighted moving averages) of both series correlated on an annual basis for the 80 year period 1880 to 1960 so that the reported correlation was extremely exaggerated and not interpretable as a simple correlation might be.
