With comparatively stable CO₂ levels over 10,500 years, temperatures still fluctuated within a range of -4 to +3 °C.

Yet, German Constitutional High Court preposterously claims there is an “almost linear relationship” between CO2 and temperature.

Junk mandated to “science” by law?

Alpine glaciers: spoilsports for the CO₂ climate hypothesis

The CO₂ introduced into the atmosphere by humans through the burning of fossil fuels is declared by today’s climate science as a “greenhouse gas” to be the decisive factor in an impending climate catastrophe. It is claimed that “never before” temperatures on earth had been rising at such rates as nowadays. The Alpine glaciers are often referred to as key witnesses to this argument. This “eternal” ice is said to be under existential threat from climate change. The “death” of glaciers is mourned on radio, in TV-shows and in the printed press. To prevent this impending catastrophe, the advanced civilization to which we owe our comparatively healthy and carefree lifestyle must be scrapped: let’s do away with coal, oil, gas and nuclear energy, with cars, steel, aluminum, concrete….and as a consequence also with modern medicine.

The United Nations assumes that the CO₂ emissions introduced into the atmosphere by humans are warming the climate due to a “greenhouse effect”. This greenhouse effect is said to endanger our existence. This thesis is propagated by its offshoot, the Intergovernmental Panel on Climate Change (IPCC), as irrefutable scientific truth. Claims to this effect are constantly repeated in countless scientific and journalistic publications. It is particularly emphasized that it is imperative to “recognize CO₂ as the principal climate control knob” ¹⁾.

In the meantime, clever representatives of the “green” climate movement have ensured that this view has even been enshrined as an incontrovertible truth in supreme court rulings by the German Federal Constitutional Court and the European Court of Human Rights (ECtHR), among others.

Since this ruling, Germany is on a one-way highway to hell into an economic and social abyss. From now on all governments are obliged to reduce CO₂ emissions to zero by 2045 ³⁾, regardless of the impact this has on the economy and the well-being of the population. Any fanatic NGO can sue the German state if it is not content with the reduction achieved. Worse still, the current greens, socialists and liberals government is already preparing further legislation to deny future governments any opportunity to revise this course again.

A law currently being prepared by (Liberal) Minister Buschmann is supposedly intended to “protect the constitutional court from undemocratic successor governments.” In reality, the new law will prevent even democratic majorities from overturning the Federal Constitutional Court ruling and the resulting regulations. Without any regard for the misery this will imply for the population.

Friedrich Merz and his conservative CDU have already signaled their support for this project.

“Natural” CO₂ levels of the past

But let’s now have a closer look at the loudly proclaimed “climate impact” of CO₂. According to the current state of climate science ⁴⁾, the CO₂ content of the atmosphere has always been below 300 ppm over at least the past 800,000 years. At times it has even been approaching the 170 ppm threshold below which some plants might be unable to survive ⁵⁾.

How “healthy” were the Alpine glaciers from about 120,000 years ago until today. Over this time, the CO₂ content fluctuated in a rather narrow range between 180 and 285 ppm, Figure 3.

The evolution of CO₂ levels shown in Figure 3 corresponds to what the IPCC calls the “stable pre-industrial state”, to which the German Federal Constitutional Court also refers in its “climate judgment”. In view of the fact that “climate science” describes the CO₂ content of the atmosphere as the “decisive control knob for the climate”, the Alps should have had a stable climatic development and a correspondingly stable glacier cover before the start of significant human CO₂ emissions.

When glaciers become climate crown witnesses

Fortunately, there is a very comprehensive study on the development of Alpine glaciers ⁷⁾, in which their extent and mass were determined using complex simulation models. There is a corresponding short film on YouTube lasting approx. 2 minutes ⁸⁾, which graphically summarizes the development of the last 120,000 years. Despite all reservations about such complex simulations, it should be noted that comprehensive geological and paleogeological studies of the entire Alpine region were used as “guard rails” for the stability of the models used. This also applies to the degree of correspondence between the end of the simulation run and the currently known state of the Alpine glaciers. Below are some still images from this video.

The comparison of Figures 4 and 5 shows that the ice cover of the Alps around 120,000 years ago was considerably less than it is today. This fact puts into perspective the terms “perpetual ice” and “dying glaciers” so often used today by the propagators of CO₂ climate alarmism. At that time, the Eemian interglacial period ⁹⁾ prevailed worldwide, one of the periodic warm interruptions of the ice ages that had prevailed for around 2.7 million years. It began around 126,000 years ago and lasted around 11,000 years. The temperature in Europe at that time was several degrees above the pre-industrial average temperature (until around 1850). During the entire Eemian period, the CO₂ content of the atmosphere only fluctuated within a narrow range between 275 and 286 ppm. There is therefore no evidence of CO₂ as the supposedly most important control knob for the climate in connection with the Eemian warm period and the subsequent glacial period.

The back and forth of the ice

The last glacial period was anything but uniform, quite the opposite. Both the temperatures and the ice volume fluctuated within wide limits, while the ice masses repeatedly buried and released enormous swathes of terrain, even outside the actual mountainous range. The following pictures give an impression of the occasionally extreme advances and retreats of the Alpine glaciers. The changing shoreline of the Adriatic Sea underscores that the sea level also fluctuated considerably during this time period.

As shown in Figure 11, the average temperatures fluctuated considerably between the end of the last glacial period and the start of the industrial age. The range was between -4 and +3 °C compared to today’s average. In contrast, during this period, CO₂ levels varied only within an extremely narrow range between 258 and 285 ppm. This does not really fit in with the purported correlation between CO₂ and temperature, which has been declared an infallible truth by the highest German court. For comparison, here is another passage from the Federal Constitutional Court’s climate ruling:

“Up to what level and at what speed the temperature will continue to rise depends on the proportion of greenhouse gases in the atmosphere and thus largely on the amount of anthropogenically emitted greenhouse gases, especially CO₂ emissions (IPCC, op. cit., pp. 17 f., 26). This is because there is an almost linear relationship between the total amount of greenhouse gases emitted and the rise in mean surface temperature (SRU, Demokratisch regieren in ökologischen Grenzen – Zur Legitimation von Umweltpolitik, Sondergutachten, 2019, p. 36)” (bold highlights added by the author).

History of Alpine glaciers does not support the CO₂ greenhouse gas hypothesis

Climate science claims that there is a linear relationship between the CO₂ content of the atmosphere, influenced by anthropogenic emissions of greenhouse gases, and temperatures on the Earth’s surface. The detailed investigation of the course of the last glacial period with regard to temperatures and ice cover in the Alps using complex simulations provides no evidence for this. Comparatively minor changes in CO₂ levels in the atmosphere are probably due to temperature-related changes in the solubility of the gas in the oceans (Henry’s law).

The same applies to the period of the current warm period over the last 10,500 years or so. With comparatively stable CO₂ levels, temperatures fluctuated within a range of -4 to +3 °C. The Alpine glaciers are therefore more like key evidence that the CO₂ greenhouse gas hypothesis is treading on rather thin ice. Whatever it is that determines our climate, it is highly unlikely to be CO₂!
