Guest Post by Willis Eschenbach I got to thinking about whether the Fourier analysis I used in my most recent post was sensitive enough to reveal the putative “harmonic solar component” which Dr...

Guest Post by Willis Eschenbach I’ve developed a curious kind of algorithm that I’ve humorously called “slow Fourier analysis”, but which might be better described as a method for direct spectral analysis...

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...
