The automatic adjustments used in global gridded data probably do a good job for what they were designed to do (remove spurious trends from global or hemispheric temperature series), but they should not be relied upon for more detailed local analysis, as Hansen et al.

It is not enough to look at global or hemispheric means of surface temperature and note that the models are not that far from producing internal variability of the right magnitude — perhaps most existing models only do this once in a blue moon, but I can imagine increasing the variance at low frequencies by a factor of two, say, so that the required magnitude is achieved more frequently.

But a recent paper by Marcia Wyatt entitled A secularly varying hemispheric climate signal propagation previously detected in instrumental and proxy data not detected in CMIP3 data base.

Hence, all these wonderful papers that CO2science has found are completely irrelevant because the don't address the actual argument that Mann et al. have made for the MWP warmth being less than the current warmth (on hemispheric or global scales).

As a result of this, when a global or hemispheric temperature reconstruction is performed, this lack of synchronicity leads to a broad, diffuse warm bump that is not as pronounced as the current warming when the warming is happening with greater synchronicity from place to the next.

This measure is available for the US from the BEST data set... The reconfirmation now of a strong sun - temperature relation based specifically upon the daytime temperature maxima adds strong and independent scientific weight to the reality of the sun - temperature connection... This suggests strongly that changes in solar radiation drive temperature variations on at least a hemispheric scale... Close correlations like these simply do not exist for temperature and changing atmospheric CO2 concentration.»
