Looking at the English-language media, one might be led to think that the latest CERN experimental results show that trees alone dominate cloud formation, by supplying the necessary cloud seeding medium. Little reference is made to cosmic rays acting as the cloud formation modulator, initiating the cloud seeding process, as hypothesized by Henrik Svensmark.
Lubos Motl at the Reference Frame noted that factions of the mainstream media seem to have spun the recent CERN papers in a “bizarre” way.

German press reports cite cosmic rays
Yet looking at the reporting by German-language scientific media, one finds plenty of mention of cosmic rays as a major player in cloud formation, which has a large cooling effect on our climate, and that erosols have been grossly misweighted in the recent climate models.
Already one year ago, in April 2015, scientists warned that the cooling effect by aerosols had been exaggerated (see our blog article “Director of the Hamburg Max-Planck-Institute for Meteorology: Aerosols cool less than previously assumed“). This appears to have been confirmed further. Within the scope of the CLOUD Project at CERN, scientists have found more indications that the aerosol effect in the models must corrected strongly downwards.”
Scinexx.de here writes that trees earlier “provided the means for lots of clouds before industrialization” and that “man obviously has influenced cloud formation [Industrialization] less than previously thought.”
So if it wasn’t human emitted particles seeding clouds before industry; and causing cooling like in the mid 20th, what could it have been? The answer according to CERN is “organic vapours emitted by trees that produce lots of aerosol particles in the atmosphere when there’s no sulphuric acid.”
How does the cloud seeding by organic tree particles work? Through nucleation-inducing cosmic rays.
Cosmic rays as the amplifier
Scienxx.de writes that scientists used the CLOUD experiment to discover this in a controlled environment and so “determine how strongly certain components in the air or certain molecules contribute to cloud formation” and “how strongly these are amplified by the energy influx through cosmic rays.”
Although the product of alpha pines occurred only in concentrations of one molecule per one trillion air molecules, they effectively contributed to cloud formation as the experiment showed. Through the influence of ions from cosmic rays, the effect increases even 10 to 100 times.”
That means cloud cover (and so cooling) would be the likely result in conditions of high cosmic ray influx into the lower atmosphere, as is the case during periods of low solar activity. Thus it appears Svensmark’s theory strengthens further.
Germany’s online wissenschaft-aktuell.de also points out the essential role of cosmic rays.
In the artificial atmosphere, scientists directed a beam of positively charged particles, so-called pions, which were generated by a Proton-Synchrotron. With this they simulated the effect of cosmic rays, which are constantly penetrating into the atmosphere. This stream of particles caused the organic molecules to ball up into approximately 2-nanometer size particles. More measurements confirmed that these volatile organic compounds grew further to form efficient condensation nuclei. In parallel the scientists underpinned the mechanism with computer models. ‘These results for me are the most important so far that the CLOUD experiment yielded so far,’ said Kirkby.”
The online Austrian science.orf.at here tells us more of the same: cosmic rays are at very much at play:
The experiment also showed that the nucleation rate rose by one or two orders of magnitude under the influence of cosmic rays. ‘This allows one to conclude that cosmic rays had a greater role on aerosols and cloud formation in preindustrial times than under today’s relatively dirty conditions,” said Paul Winkler of the Department of Aerosol Physics and Environmental Physics at the University of Vienna.”
In their press releases the government-paid scientists can add the mandatory “the-warming-continues” remarks all they want, but one thing is clear: The models have a long way to go and they are in dire need of major revamping. CO2 is nowhere near as important as some want us to believe it is. Cosmic rays, modeulated by the sun’s magnetic field, are together a factor that need to be accounted for.
It’s time for the habitual solar-denying so-called “experts” to acknowledge this and to start modelling much more accurately. We’ve known this for years already.
