That sees to me to be a dramatic accomplishment of Steve McIntyre and his statistical colleagues here at Climate Audit.

How sad that people in climate science cannot acknowledge this with candor.

As usual in ClimateScience-TM no one wants to be explicit in taking on Mann and his attack dogs (lap dogs?).

Yet, one does not need to read behind the lines to see that Frank-Esper-Zorita-Wilson were not expressing anything like Mann’s confidence that the field of paleo climatology has moved steadily forward with all the Mann associates reconstructions.

]]>But the contention, in broader terms, that E&E has no impact, seems strange in the light of the amount of abuse it gets. Why bother about circulating all the false suggestions that it doesn’t do peer review etc etc, if it is so insignificant?

]]>Thompson prefers to combine d18O records from different sites into a single index by first converting each series to z-scores.

I don’t see the point of this either, since any physical meaning of the scale of the series is lost when you scale by standard deviation, which is extraneous to whatever response there is of d18O to mean annual temperature.

But still, it is what should be a well-defined linear formula. The coefficients will differ depending on how the standard deviations were computed — over the entire life of each core, over the common life of all cores considered, over the study period, using annual numbers or 5-year averages or 10-years averages, etc. But whatever method was used, the coefficients should be recoverable by regressing the index on the data series used.

My problem with the PNAS paper is that there is no such formula relating the decadal 2006 PNAS version of “Dr. Thompson’s Thermometer” to decadal averages of the underlying data he claims it was computed from.

]]>Steven Chu also uses what appears to be a Hockey Stick in “The Energy Problem”.

It’s on page 7 of the pdf.

ClimateAudit was probably aware of this already though.

**[Thanks — Indeed Steve has already started a thread on this topic, “Spot the Hockey Stick, #n”. Evidently the HS itself is alive and well. Please discuss over there.]**
