By your persevering studies in thermometry you have deserved well of physics and chemistry; but you have gained your scientific laurels mainly in
Young children typically aren't able to comply with the procedures required to obtain temperature readings with oral thermometers so they often are subject to rectal thermometry, which is uncomfortable for them, their parents and healthcare workers.
Furthermore, the methods used to convert the proxy measurements (thermometry or tree rings) into useful global data (gridded average temperatures) are tricky, subject to conscious and unconscious bias, and require the use of a bunch of software that, from all evidence, is garbage.
Any data before that is suspect, as is shown by the valid debates over the shape of the curves — even in the thermometry era.
That being said, surface temperature proxies, whether adjusted thermometry or tree rings are not very convincing data, because of the poor relationship between individual surface measurements and global heat content due to micro-climate, micro-meteorological and other factors, and the dramatic spatial under-sampling of the data set.
Steve M. has continued his relentless examination of proxy thermometry and continues to find it entirely wanting.
Quayle, Karl et al in 1991 did a study of the differences between the liquid in glass readings from the Stepehenson Screen, (AKA cotton region shelter)and the electronic MMTS (Maximum Minimum Temperature Sensor) equipment which replaced the liquid in glass thermometry circa 1990.
Obviously, they were early-type climatologists from the Medieval CRU at East Anglia, setting the ground for their precision thermometry.
Thank you for the citation correction and for the reference to Barker et al 2005, which is indeed an excellent review of Mg/Ca thermometry.
Unfortunately, borehole thermometry in ice is a sensitive measurement that neccesarily has to be made in harsh conditions at least several years after all drilling has stopped, and hence is rarely every done, so only a few such reconstructions exist.
