Problems With The Scalpel Method

Guest Post by Willis Eschenbach In an insightful post at WUWT by Bob Dedekind, he talked about a problem with temperature adjustments. He pointed out that the stations are maintained, by doing things like periodically cutting back the trees that are encroaching, or by painting the Stevenson Screen. He noted that that if we try…

The Slow Fourier Transform (SFT)

Guest Post by Willis Eschenbach While investigating the question of cycles in climate datasets (Part 1, Part 2), I invented a method I called “sinusoidal periodicity”. What I did was to fit a sine wave of various periods to the data, and record the amplitude of the best fit. I figured it had been invented…

Solar Periodicity

Guest Post by Willis Eschenbach I was pointed to a 2010 post by Dr. Roy Spencer over at his always interesting blog. In it, he says that he can show a relationship between total solar irradiance (TSI) and the HadCRUT3 global surface temperature anomalies. TSI is the strength of the sun’s energy at a specified distance…
