In this contribution I show you the results of a cycle analysis of 2,000 years of global climate data, the result of which is that Earth’s climate is determined by three main cycles, and that CO2 plays only an insignificant role.

But first let me mention how I became interested in the question of Earth climate. My research subject was everything related to lasers. Physics of Lasers, technical and scientific applications, e.g., spectroscopy and atomic clocks based on one singe atom, etc., etc. Even in the 1990s, for persons with scientific education, the self-contradictions of the official climate propaganda were obvious. Thus, the official narrative could not be true. We joked about the primitivity of the propaganda.

I did not have time to look deeper. I had 40 scientific coworkers, 10 of whom, to feed them, I had to find about $1 million each year. So that did not give me much time. But at retirement I had time. First I looked into the official models, and it is quite obvious where the fudge factors in the calculations are. But, then, I am an experimental physicist, so I got together with Horst Luedecke to analyze climate measurements.

In particular we did what is called Fourier Analysis, which means looking for cycles in seemingly irregular measurements in time series. Since this is the most common type of analysis in any field of physics or technology, we were surprised not to find any such work in the half-million publications of the climate literature. But then we said, “OK, if nobody did that so far, well, we will do that.” We published our analysis, and the reviewers confirmed that our work and conclusions were correct.
