The Revenge of the Climate Reparations

Guest Post by Willis Eschenbach Much of the current angst at the UN regarding climate has to do with the idea of “climate reparations”. These are an imaginary debt supposedly owed by the major CO2 emitting nations to the countries … Continue reading

The Price Tag Of Renewables, Part 2

Guest Post by Willis Eschenbach Anthony has posted a story about a laughable analysis of the cost of propping up renewables through subsidies. And long-time WUWT contributor KD helpfully pointed me to the document itself. Now that I have the actual document, … Continue reading

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 … Continue reading

Maunder and Dalton Sunspot Minima

Guest Post by Willis Eschenbach In a recent interchange over at Joanne Nova’s always interesting blog, I’d said that the slow changes in the sun have little effect on temperature. Someone asked me, well, what about the cold temperatures during … Continue reading

Well, Color Me Gobsmacked!

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. The basic concept is quite simple. I fit … Continue reading

The Effect of Gleissberg’s “Secular Smoothing”

Guest Post by Willis Eschenbach ABSTRACT: Slow Fourier Transform (SFT) periodograms reveal the strength of the cycles in the full sunspot dataset (n=314), in the sunspot cycle maxima data alone (n=28), and the sunspot cycle maxima after they have been … Continue reading

The Tip of the Gleissberg

Guest Post by Willis Eschenbach A look at Gleissberg’s famous solar cycle reveals that it is constructed from some dubious signal analysis methods. This purported 80-year “Gleissberg cycle” in the sunspot numbers has excited much interest since Gleissberg’s original work. … Continue reading

Sailing on the Solar Wind

Guest Post by Willis Eschenbach The lack of cycles in the solar wind isn’t surprising when you analyze this paper. There is very little sign of any kind of annual cycle, which makes perfect sense because the sun doesn’t run … Continue reading

Cycling in Central England

Guest Post by Willis Eschenbach Looking at a recent article over at Tallbloke’s Talkshop, I realized I’d never done a periodogram looking for possible cycles in the entire Central England Temperature (CET) series. I’d looked at part of it, but … Continue reading

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 … Continue reading

The Elusive ~ 60-year Sea Level Cycle

Guest Post by Willis Eschenbach I was referred to a paywalled paper called “Is there a 60-year oscillation in global mean sea level?”  The authors’ answer to the eponymous question is “yes”, in fact, their answer boils down to “dangbetcha … Continue reading

A Modtran Mystery

Guest Post by Willis Eschenbach I’ve been messing about with the “Modtran” online calculator for atmospheric absorption. It’s called “Modtran” because it is a MODerate resolution program to calculate atmospheric infrared absorption written in ForTRAN, which calculates the result for each 1 … Continue reading
