Darwin and GHCN Adjustments

Willis Eschenbach created a stir a few days ago with his post at WUWT entitled The Smoking Gun At Darwin Zero. Darwin Zero is one of five duplicate Darwin records in the GHCN database. It is the longest, and the others seem to be fragments of it, although there are some variations.

The claim is that the homogeneity adjustments are so large, and upward, that they indicate manipulation. This stern statement was underlined:
Those, dear friends, are the clumsy fingerprints of someone messing with the data Egyptian style ... they are indisputable evidence that the "homogenized" data has been changed to fit someone’s preconceptions about whether the earth is warming.

I've heard of occasional problems with downloading R code. I think cut and paste should generally work, but I'm trying to now post copies of files on a document store.
