COMMENT ON James Hurrell, Gerald A. Meehl, David Bader, Thomas L. Delworth, Ben Kirtman, and Bruce Wielicki 2009: A Unified Modeling Approach to Climate System Prediction. Bull. Amer. Meteor. Soc., in press

The authors of this paper (and that of Palmer et al. 2008) should be commended for moving toward a more integrated perspective of climate prediction. The authors of this paper, however, do not present a completely new perspective as they claim in their text when they write "There is a new perspective of a continuum of prediction problems, with a blurring of the distinction between short-term predictions and long-term climate projection". They, unfortunately, do not yet accept the implications of their new perspective to multi-decadal and longer time period climate prediction.
