‘Her first mistake — quite an embarrassing one really — was to assume that this [POGA C] was the influence of ENSO on global temperature history. This quite misses the point, that one of the strengths of the new approach is that it allows climate forcing and ENSO to interact in a nonlinear manner. The actual estimate of the influence of ENSO, according to the new research, is shown in the graph labelled “POGA-H minus HIST.” ‘
Excuse me, but who is making the assumption? Tamino is assuming that natural regularities such as ENSO cannot be investigated empirically and independently of the standard assumptions of the “radiation-only” crowd. If Mr. Tamino thinks that I am wrong then I am sure that he will explain how empirical investigation of ENSO Could Not reveal a role for ENSO that is greater than what he estimates and that is independent of an “radiation-only” account.
