Fred
Here is an example.
The physical explanation based on ocean heat content and the negative constraints imposed by the Stefan-Boltzmann law (precluding runaway type climate feedbacks) is what shows the role of natural fluctuations to be no more than minor (at least for the 1956-2005 interval).
You claimed “the role of natural fluctuations to be no more than minor”. This is just a claim. There is no evidence for your claim. It is just story telling.
Fred, is not the “natural fluctuation” described in the following paper major?
