Excerpt: Ryan O’s latest work on statistical evaluation of the Steig et al “Antarctica is warming” paper ( Nature, Jan 22, 2009) I thought long and hard about the title, especially after reviewing the previous work from Ryan O we posted on WUWT where the paper was dealt a serious blow to “robustness”.
After reading this latest statistical analysis, I think it is fair to conclude that the paper’s premise has been falsified. Ryan O, in his conclusion, is a bit more gracious: “I am perfectly comfortable saying that Steig’s reconstruction is not a faithful representation of Antarctic temperatures over the past 50 years and that ours is closer to the mark.” […]
It is my view that all Steig and Michael Mann have done with their application of RegEm to the station data is to smear the temperature around much like an artist would smear red and white paint on a pallete board to get a new color “pink” and then paint the entire continent with it. It is a lot like “spin art” you see at the county fair. For example, look (at left) at the different tiles of colored temperature results for Antarctica you can get using Steig’s and Mann’s methodology.
