As CA readers are aware, key findings of Santer et al 2008 do not hold using updated data. Ross and I submitted a comment to IJC showing this. The comment was rejected twice, with one of the reviewers (as in the case of the comment on Steig et al) being a Santer coauthor (who was not identified to us as such). Ross eventually managed to get similar results published in another journal.
Jean S points out in a comment on the Steig thread that our findings were completely misrepresented by IPCC AR5 (ZOD) chapter 10 (also the source of disinformation about Steig).
Our article stated that there was a statistically significant difference between models and observations in the tropical troposphere. Instead of citing our articles as rebutting Santer’s assertions, IPCC cites us as endorsing Santer’s false assertions:
The claim by Douglass et al. (2008) that modeled and observed trends in the tropical troposphere for the period from 1979 to 1999 are significantly different is contradicted by Santer et al. (2008) and McKitrick et al. (2010). The findings of Santer et al. (2008) are based on analyzing updated radiosonde and satellite datasets, considering observed and simulated trend uncertainties due to natural variability. Santer et al. (2008) also provide evidence based on synthetic data that the consistency test applied by Douglass et al. (2008) leads to incorrect conclusions.
They go on to make the following absurd statement:
Taking these studies together, we conclude, that apparent differences between tropical free tropospheric temperature trends in models and observations and differential warming in the tropics over the period 1979–1999 are unlikely to be statistically significant after fully accounting for observational uncertainties.
Watch the pea. The issue with Santer was that key results fell apart over the longer period of 1979-2009 (or 2010 or 2011) as opposed to the 1979-1999 period. As noted above, realclimate spoke out strongly against Courtillot’s analysis which didn’t use up-to-date data. Pierrehumbert alleged that such analysis was dishonest. Why should different standards apply when employed by IPCC chapter 10?
