IPCC KNEW FROM START CLIMATE DATA INADEQUATE

In 1999, the National Academy of Sciences, the research arm of the National Research Council, released a study expressing concern about the accuracy of the data used in the debate over climate change. They said there are,
“Deficiencies in the accuracy, quality and continuity of the records,” that “place serious limitations on the confidence that can be placed in the research results.”
Karl chaired the study, so he knew better than any that to achieve the results they wanted, namely a steadily increasing temperature over the 120 + years of instrumental record, was made easier by the inadequacy of the data. They ignored the fact that the inadequacy of the data negated the viability of the work they planned and did. For example, the extent, density, and continuity of the data are completely inadequate as the basis for a mathematical computer model of global climate. In short, they knew they would have to create, make up, or modify data to even approximate a result. The trouble is the data was so inadequate that even with their actions the results could not approximate reality.
