The scientist at the Potsdam Institute for Climate Impact (PIK) is an oceanographer who has studied physics before his professional training. He is therefore familiar with thermodynamics and its second law, which states that with each change of the state, “diseases” increase, also known as entropy. This is reflected in warming. Growth entropy is the basic feature of our universe. Everything tends to be confused without an investment job.

You may be familiar with this phenomenon. The growing entropy also prevents permanent motion of the machine. Each working machine also creates friction, so useful energy is inevitably lost. So, what does this have to do with Stefan Rahmstorf?

He posted the following post on Twitter (now X) on January 14, 2025:

[In English: “Nuclear energy, whether from fusion or fission, has the problem of waste heat, just like fossil fuel energy. It is still small compared to CO2, but it will soon become a relevant warming problem with the growing energy demand by mankind.”]

In his tweet, he complained that nuclear energy produces waste heat, and therefore would represent another related problem on our planet, which is due to the warming of greenhouse gases.

Smart readers will rememberphysicist Professor Harald Lesch also advocated this paper precisely, even in the teacher’s speech (!). He also failed to take into account all the converted energy (whether from wind, sun or heat) that ultimately leads to an increase in entropy, i.e. heating. It all depends on orders of magnitude.

If humans generate energy by burning carbon (which leads to the production of the “greenhouse” gas CO2), the problem is a higher order of magnitude. It reduces heat escape by radiating into space and accumulates effects in the atmosphere, waste heat does not. This has long been known from the scientific literature.

In January 2025, what is the share of low CO2 electricity in Germany's total consumption?

Total solar, wind and hydropower consumption

What is the total consumption of carbon combustion, the “rest” in the chart? Unfortunately, the average for the month was 61%, or just 39% of low-carbon electricity. If you analyze the hourly data for “Agora Energiewende”, it fluctuates between 9% excellent 9% and 93% totally under.

In Germany, 90 GW of solar energy and 69 GW of low CO2 wind energy have been installed; if the “installation capacity” is also available, only about half of the renewable capacity capacity can be used.

However, in fact, PV contributes only 2% to total consumption on average, 29% wind energy, with a large fluctuation range between 1.7% and 67%. Therefore, renewable energy alone is not really suitable for solving carbon dioxide emissions. The weather is too variable at about 50° north latitude. This would be the logical conclusion of “climate enthusiasts”, such as professors Stefan Rahmstorf and Harald Lesch.

And why, no matter what the weather is, why are you still completely opposed to the excuse of low CO2 generation from nuclear power generation? We don't know. We only know that they are talking nonsense to oppose low CO2 technologies, which is also the sixth assessment report on the Climate Commission’s recommendations of the IPCC, namely the III Working Group, which is a necessary supplement to renewable energy.

Skeptics of the greenhouse effect are sometimes correctly accused of denying climate issues. However, Rahmstorf, Lesch and the Company (Co.

They are very effective in hindering solutions to the problem. Finally, whether you don’t want to see a challenge or just with the help of false arguments, whether you don’t want to see a challenge or not fully accept it, there will be no impact.
