If Watts were correct, this would be a major problem. If the entire US temperature record was unreliable, then conclusions drawn from the temperature record could also be similarly flawed. At a minimum, the scientific papers using the temperature record would have to be revisited. So a thorough investigation of Watts’ conclusion by scientists was warranted. And now a new peer-reviewed paper by scientists at the National Climate Data Center (NCDC) have analyzed the temperature record and found that Watts’ conclusion of a flawed temperature record runs contrary to the actual data.
