Hi Keith,

suggested wording:

Brger et al. 2005 show that paleo-driven regression models strongly 
depend on the details of the data processing, finding an entire range of 
climate histories. This uncertainty can be traced back to an unjustified 
extrapolation of the regression laws beyond their calibration scale, a 
fact which is particularly critical for the parameter-loaded versions of 
the multiproxy type (cf. Brger and Cubasch 2005).
