That notwithstanding, Huang et al, 2008 come to a similar conclusion as other recent studies (e.g. AR4 and Mann et al, 2008) regarding the «MWP» — that while it is indeed evident in hemispheric mean reconstructions, it does not reach the level of the warmth of recent decades.

Our examination does suggest that a slight modification to the original Mann et al. reconstruction is justfiable for the first half of the 15th century (∼ +0.05 — 0.10 º), which leaves entirely unaltered the primary conclusion of Mann et al. (as well as many other reconstructions) that both the 20th century upward trend and high late - 20th century hemispheric surface temperatures are anomalous over at least the last 600 years.

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. (1999) warned: «We recommend that the adjusted data be used with great caution, especially for local studies.»

Only by amalgamating all of the records we have (after correcting for known problems, such as discussed below) can we have an idea what the regional, hemispheric or global means are doing.

Ash should not be an issue as fallout is only significant in regions proximate to an eruption — there is no hemispheric - scale ash deposit associated with these eruptions.

In forming a hemispheric composite, these errors thus lead to a smearing out of the signal back in time as slightly different age model errors accumulate in the different regions contributing to the composite.

Like I say, you see a richness of behaviour in the models including in some occasions behaviour that at first sight looks not dissimilar to that highlighted in the observations by the Thompson paper and this on top of the «external control» as we called it in our 2000 paper in Science of the external forcings in a particular model which drives much of the multi-decadal hemispheric response in these models and which, in terms of the overall global warming response, is dominated by greenhouse gases.

You'll see a diurnal cycle (as a function of the continental configuration) and an annual cycle as a function of the imbalance in hemispheric seasonality.

As a result, ice cores are a regional (not hemispheric, and certainly not global) temperature proxy.
