Curry on being teased and misleading graphs

Figure 5. Result of the Berkeley Average Methodology applied to the GHCN monthly data. Top plot shows a 12-month land-only moving average and associated 95% uncertainty from statistical and spatial factors. The lower plot shows a corresponding 10-year land-only moving average and 95% uncertainty. This plot corresponds to the parameter in Equation 5. Our plotting convention is to place each value at the middle of the time interval it represents. For example, the 1991-2000 average in the decadal plot is shown at 1995.5.

I did not say that “the affair had to be compared to the notorious Climategate scandal two years ago,” this is indirectly attributed to me. When asked specifically about the graph that apparently uses a 10 year running mean and ends in 2006, we discussed “hide the decline,” but I honestly can’t recall if Rose or I said it first. I agreed that the way the data is presented in the graph “hides the decline.” There is NO comparison of this situation to Climategate. Muller et al. have been very transparent in their methods and in making their data publicly available, which is highly commendable.

I have dug into my memory. Rose brought up hide the decline in our first interview, in the context of the plot that ends in 2006. He called me back specifically to discuss this and teased the “hide the decline” out of me.

There is no question that the diagrams and accompanying text in the IPCC TAR, AR4 and WMO 1999 are misleading. I was misled.
It is obvious that there has been deletion of adverse data in figures shown IPCC AR3 and AR4, and the 1999 WMO document. Not only is this misleading, but it is dishonest (I agree with Muller on this one). The authors defend themselves by stating that there has been no attempt to hide the divergence problem in the literature, and that the relevant paper was referenced. I infer then that there is something in the IPCC process or the authors’ interpretation of the IPCC process (i.e. don’t dilute the message) that corrupted the scientists into deleting the adverse data in these diagrams.
