I know you mean well, wygator, but I am not seeing the point of the above post. You seem to labor under a mistaken belief that NASA/GISS explaining adjustments to the data--not to mention documenting how and why they did it--is some kind of admission to some prior deceit or misbehavior is somehow a bad thing. Adjusting data is a regular and absolutely essential step in the process of organizing and preparing data for statistical modeling. If there are problems with their methodology, you don't provide. Maybe I am misreading your post, but perhaps you take issue with the upward trend adjustment?
