Harris and Chapman [2001; hereafter HC2001] recently presented a comparison between ground temperature records (temperature–depth profiles measured in many boreholes) and surface air temperature observations and reconstructions. Research such as theirs, attempting to reconcile or compare climate proxies that have high temporal resolution with those that have much lower temporal resolution, is important because it provides a way of assessing the fidelity with which the high-resolution proxies capture multicentury climate variability [Briffa and Osborn, 1999, highlighted some potential difficulties at capturing such long time scale variations]. Unfortunately, the paper by HC2001 contains a conspicuous error that requires highlighting in order that their results can be re-evaluated, but also to prevent the error from propagating in the literature.
