First, the computer climate models on which predictions of rapid warming from enhanced atmospheric greenhouse gas concentration are based «run hot,» simulating two to three times the warming actually observed over relevant periods — during which non-anthropogenic causes probably accounted for some and could have accounted for all the observed warming — and therefore provide no rational basis for predicting future GAT.

On average, models simulate more than twice the observed warming over the relevant period.

[¶]... Basing our assessment on a combination of several independent lines of evidence, as summarised in Box 10.2 Figures 1 and 2, including observed climate change and the strength of known feedbacks simulated in GCMs, we conclude that the global mean equilibrium warming for doubling CO2, or «equilibrium climate sensitivity», is likely to lie in the range 2 °C to 4.5 °C, with a most likely value of about 3 °C.

Recent work (e.g., Hurrell 1995, 1996; Thompson and Wallace 1998; Corti et al., 1999) has suggested that the observed warming over the last few decades may be manifest as a change in frequency of these naturally preferred patterns (Chapters 2 and 7) and there is now considerable interest in testing the ability of climate models to simulate such weather regimes (Chapter 8) and to see whether the greenhouse gas forced runs suggest shifts in the residence time or transitions between such regimes on long time - scales.
