Many palaeoclimate studies have quantified pre-anthropogenic climate change to calculate climate sensitivity (equilibrium temperature change in response to radiative forcing change), but a lack of consistent methodologies produces awide range of estimates and hinders comparability of results.

In using AOGCM output in this way, it is important not only to demonstrate that these unforced simulations do not drift significantly (Osborn, 1996), but also to evaluate the extent to which model estimates of low - frequency variability are comparable to those estimated from measured climates (Osborn et al., 2000) or reconstructed palaeoclimates (Jones et al., 1998).
