#37 CC: We don’t actually know that. Taking a bunch of data from different sources, with different standards, is going to require some corrections. As Dr Pielke said when I asked the same question: “As we wrote in our 2007 JGR paper, there are major problems with the quantitative accuracy of the surface temperature data. As you correctly summarize, the adjustments are often larger than the trends.” That doesn’t mean the corrections are necessarily wrong. On the other hand, when they “they have failed is in preventing, in their leadership position, a proper scientific debate of the issues” it’s damned hard to tell if they’re correct or not.
