you do realize that this story which started in the Daily Mail, has already been discredited?  The response was swift: Several climate researchers, including former NOAA scientists, wrote blog posts pointing out the many flaws in Bates’ argument. Chief among them is the fact that the datasets, along with a record of bug fixes and their impact is publicly available. In addition, multiple papers have drawn the same conclusions as Karl et. al using the same dataset, and another recent paper backs up the reliability of the NOAA’s models. All of the research points to a mostly uninterrupted trend of warming throughout the 20th and into the 21st century.
