As far as this historic period is concerned, the reconstruction of past temperatures based on deep boreholes in deep permafrost is one of the best past temperature proxies we have (for the global regions with permafrost — polar regions and mountainous regions)-- as a signal of average temperatures it's even more accurate than historic direct measurements of the air temperature, since the earth's upper crust acts as a near perfect conservator of past temperatures — given that no water circulation takes place, which is precisely the case in permafrost where by definition the water is frozen.

If you wanted the global / regional / local averages to somehow provide a measure of average human misery due to increasing temperatures, then population - weighted or un-weighted averages will probably capture that, since the density of met stations is a reasonable proxy for population density.

the problem is that this definition implicitly assumes that the global, time average surface temperature is a definite single valued function of the radiative average forcing, which is far from being true since there are considerable horizontal heat transfer modifying the latitudinal repartition of temperature: the local vertical radiative budget is NOT verified.
