In the preceding post we examined criticism of one of the Berkeley team’s papers, Decadal Variations in the Global Atmospheric Land Temperatures (Muller et al. 2011, hereafter referred to as M2011), by a fake skeptic. Now I’ll offer my own critique.
The more I study this paper, the less I like it. There are a few serious problems and some bogus numbers. They’ve taken steps which don’t invalidate analysis but do make it a helluva lot harder. And there are unanswered questions which are relevant to the central theme. In fact the more I think about it … maybe I was to hard on Doug Keenan? Nah.
I have quite a lot to say about this paper, so I’m going to do so in two posts. In this, the first, I’ll address some of the statistical issues as well as one of the central results.
