Sun, clouds and climate – a post from an EIKE reader

In a conversation with the EIKE editorial team, our reader Garik Müller noted that recent solar storms have promoted cloud formation – which would contradict the Svensmark-Shaviv effect and the Forbush effect.
But the Earth’s atmosphere is known to be much more complicated than the computer models of climate researchers – solar radiation can also have a different effect under different circumstances.
A discussion article by Garik Müller
Question from EIKE:
When there is a lot of solar wind, the particles from space are deflected away from the earth, the Forbush effect. If there are fewer particles, there are fewer cloud nuclei. The recent solar ejections should therefore have reduced the clouds, nnless certain solar events produce particles that can penetrate the van Allen belt.
Garik Müller:
It is high-energy radiation that comes both from the cosmic realm and is emitted towards the Earth during certain solar activities. Usually the starting point on the sun points away from the Earth. This time, however, the Earth was directly in focus. Due to the cascade effect, the ionizing radiation reaches the troposphere.
The Forbush effect actually only works if the “solar storm” points towards the Earth at the same time.
If it is offset in time, it does not have such a strong effect.
However, the Svensmark-Shaviv effect, which I believe to be conclusive and correct after having studied it for a long time, is only the first stumbling block in events like this year and is far more strongly influenced by the sun. There was still little cloud cover until the beginning of June. As a result, we had higher global surface temperatures, which subsequently fell, as the evaporation rate over the oceans increased considerably, which in turn led to a partial fall in sea surface temperatures, especially in the Atlantic and Pacific.
After that, there was a period of increased solar activity, as I was able to learn from observations of a friend in Frankfurt. Whenever large-scale cloud formation began, the number of sunspots were considerably higher. This has also been the case recently. It has also been interesting to observe that the processes were always congruent in time.
If you then take the work of Zharkova, it seems striking that such events seem to accumulate towards the end of a solar maximum, which then often coincides with local weather phenomena such as the current one, which again raises many questions. It becomes unpleasant when the flow systems intensify the whole thing together with the topographical conditions.
The reactions from the climate hysterics are neither helpful nor appropriate. BBut then it becomes so mathematically complex that 99.9% of scientists can hardly describe it. Meticulous work would be necessary. This cannot be done using existing algorithmic models because the models would then crash.
This is the point where mathematics catches up with conventional theory. There is some work on this, but you won’t find anything about it without targeted research.
The idea came to me when I thought of my work on meson passages in this context. The theoretical foundations from this are very helpful for this topic.
