In the 19th century, British Prime Ministers used to say there were “lies, damned lies, and statistics”. In the 21st century, we may say there are frauds, serious frauds, and IPCC Assessment Reports. Recall, for instance, the notorious graph in the Fourth Assessment Report that falsely indicated that the rate of global warming is accelerating and we are to blame. Using the same statistical dodge, one can show that a sine-wave has a rising trend.
