I don't think these new results will in any case affect the
yearly mean
temperature grid calculations, as they depend on actual surface station
temperature records — which both we and Steig et al. used — and not on
reconstructed gridded data.
The TAR discussed various attempts to use proxy data to
reconstruct changes in the average
temperature of the NH for the period after AD 1000, but focused on three reconstructions (included in Figure 6.10), all with
yearly resolution.
