GLOBAL WARMING: LOOKING FOR PERIODICITIES IN TEMPERATURE DATA joannenova.au/2013/05/fourier-analysis-reveals-six-natural-cycles-no-man-made-effect-predicts-cooling/ This is interesting, but I have to think about it. Im not yet convinced that the longest & by far most dominant period they find, 250-years, isnt an artifact of the DFT (Discrete Fourier Transform) itself, possibly a result of applying a DFT to an aperiodic function.
