Scafetta vs the IPCC

Great new application from WUWT contrasts the predictions of two models of global warming, Scafetta’s empirical resonance model and the IPCC general circulation models.

I was asked to make sense of this from Rahmstorf and Foster:, referenced here at RC:

I haven’t read the paper in detail, and I find I have to do that to really assess it. So I can only comment on the general approach. Although it seems superficially plausible, its also somewhat novel, and so I am uncomfortable with it, as I don’t fully appreciate the statistical limitations.

IMHO only really scientific way to approach a question is to contrast between competing hypotheses, eg. the null versus the alternative, or other combination, such as the Scafetta vs IPCC above. Its clear, easy to understand and not so prone to biases.

But it seems like climate scientists are very creative in coming up with novel ways to justify their theory, and almost always fail to clearly compare and contrast the alternatives. That is their weakness, they are so damn convinced of CAGW, and shows they are generally ill-equipped with the expertise and training for conducting rigorous scientific analysis.

And of course, “creative” is meant not in the good sense.
