This is a common misconception in discussions about scientific fraud. You don't have to be able to do a thing correctly to detect when it's being done incorrectly. You shouldn't trust any claims by scientists about global trends in mean temperatures. We can say this with confidence, without being able to compute a better timeseries, by just looking to see if the basics of the scientific method are being followed by those who do it. If we do that check we find that they don't follow the scientific method. Specifically, they edit past observations to bring them into line with theory instead of deriving theory from data believed to be robust. https://retractionwatch.com/2021/08/16/will-the-real-hottest-month-on-record-please-stand-up/ https://retractionwatch.com/2021/08/16/will-the-real-hottest...
