AR5 Figure 1.4 Having deleted the informative (perhaps too informative) SOD Figure 1.5, IPCC's only comparison between AR4 projections and actuals is in the revised Figure 1.4, a figure that seems more designed to obscure than illuminate.

AR4 Figure 10.26 Richard Betts recognized that there was no location error in connection with AR4 projections, but argued (see here) that the comparison in AR5 Figure 1.4 was «scientifically better» than the comparison in the SOD figure which, as Betts acknowledged, was «based on» an actual AR4 graphic (AR4 Figure 10.26).
