I canโ€™t let the patent absurdity of Andrew Revkinโ€™s Dot Earth blog item from last evening go unremarked. Revkinโ€™s spin on the forthcoming Nature report is that they are predicting cooling now because they wanted to make their models more realistic. Titled โ€œMoving from Projections to Predictions on Climate,โ€ the piece speaks for itself.

Scientists are forecasting a temporary cooling, from shifts in the oceans including the Pacific Decadal Oscillation, which has cool and warm phases shown in this graph.

The researchers, writing in the journal Nature, stress that this is a preliminary attempt to shift climate models toward becoming a forecasting tool, mainly by tweaking them with real-world data (in this case ocean temperatures) as they churn through their simulations.

What a novel idea, โ€œtweakingโ€ climate models with โ€œreal-world dataโ€ so that they can forecast actual climate phenomena. What does that tell you about what the climate models were designed to do previously?
