However, models would need to underestimate variability by factors of over two in their standard deviation to nullify detection of greenhouse gases in near - surface temperature data (Tett et al., 2002), which appears unlikely given the quality of agreement between models and observations at global and continental scales (Figures 9.7 and 9.8) and agreement with inferences on temperature variability from NH temperature reconstructions of the last millennium.

A recent study by Cowtan et al. (paper here) suggests that accounting for these biases between the global temperature record and those taken from climate models reduces the divergence in trend between models and observations since 1975 by over a third.
The growing divergence between models and observations even on a global average, and the lack of mathematical foundation to the statement that the fluctuations between runs of the same models and between runs of different models «are noise» [73] forbids their use as justification of economic or political decisions.
IPCC authors added a grey envelope around the AR4 envelope, presumably to give rhetorical support for their false claim about models and observations; however, this envelope did not occur in AR4 or any peer reviewed literature.
