     Hi Keith,

     would love reprints  - suggested wording also welcome and will judge if/how to include

     suggested wording:
     Bürger 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. Bürger and Cubasch 2005).
