CERN experiment confirms cosmic ray action

Russ Steele

We have all be waiting for the CERN Results, even though early experiments confirmed that Svensmark’s hypothesis had merit —  cosmic rays cause clouds to form. The wamers kept say wait for the CLOUD results. Well the results are in and cosmic rays cause clouds and clouds cool the earth.  Nigel Calder has the details at Calder’s Updates.

Long-anticipated results of the CLOUD experiment at CERN in Geneva appear in tomorrow’s issue of the journal Nature (25 August). The Director General of CERN stirred controversy last month, by saying that the CLOUD team’s report should be politically correct about climate change (see my 17 July post below). The implication was that they should on no account endorse the Danish heresy – Henrik Svensmark’s hypothesis that most of the global warming of the 20th Century can be explained by the reduction in cosmic rays due to livelier solar activity, resulting in less low cloud cover and warmer surface temperatures.

Willy-nilly the results speak for themselves, and it’s no wonder the Director General was fretful.

Jasper Kirkby of CERN and his 62 co-authors, from 17 institutes in Europe and the USA, announce big effects of pions from an accelerator, which simulate the cosmic rays and ionize the air in the experimental chamber. The pions strongly promote the formation of clusters of sulphuric acid and water molecules – aerosols of the kind that may grow into cloud condensation nuclei on which cloud droplets form. What’s more, there’s a very important clarification of the chemistry involved.

If you want to understand the full implication of this confirmation of “Svensmark’s hypothesis that most of the global warming of the 20th Century can be explained by the reduction in cosmic rays due to livelier solar activity, resulting in less low cloud cover and warmer surface temperatures,” you will need to read The Chilling Stars: A New Theory of Climate Change by Svensmark and Calder.

Stay tuned, there will be counter attack by the warmers, and this finding destroys the CO2 myth that it is the cause of global warming.  No, a more active sun reduces the cosmic ray from reaching the earth, a quiet sun results in more cosmic rays and more earth cooling clouds. The warmers cannot allow that to become common knowledge, as it will destroy their grant money stream.

    Much as I’ve enjoyed reading Calder’s blog, I’ve not read the book. A free version that is more information dense and, if you are able to read a Scientific American article it should be understandable, is Svensmark’s Cosmoclimatology piece in Astronomy & Geophysics of about the same time:

    When I found it in early 2007 I combed through the citations, and it was Shaviv & Veizer ’03 (see Fig. 8) that convinced me Galactic Cosmic Rays were a known basic forcing the IPCC had ignored that had to be correctly accounted for before any IPCC result could be taken seriously.

    It should also be noted that the CLOUD experiment was all set to go in the late 90’s but its funding was killed by IPCC politics. It was the Svensmark SKY experiment in 2006 that broke the funding logjam, allowed the prototype CLOUD-06 apparatus to be assembled and, from what the CLOUD collaborators learned from that, the current CLOUD-09 was designed and built.

    Had politics not interfered with science, we’d have gotten this result in ’03, BEFORE AB32 was rammed down the throat of Californians.

    That should have been “Figure 8” of the Cosmo paper for SV03, “Celestial driver of Phanerozoic climate?”.

    I read “The Chilling Stars” and watched the documentary on Youtube.
    Henrik Svensmark is a true scientific hero and deserves a Nobel Prize.

    BTW Russ, WordPress apparently thinks you are on Zulu/Coordinated Universal/Greenwich Mean time, not Pacific…

      Thanks for the tip, it is fixed.

    The cloud chamber results are pretty important. It certainly takes a jab at standard GHG warming theory accounting for all of the warming of the late 20th century. How many times have we heard that they can’t think of any other explanation so it must be CO2. However, as much as I like these results, I think the GCR theory is only part of the story. There certainly has been a lot of extreme weather over the last couple of years. Svensmark’s GCR does not explain that. The ocean cycles like the PDO and AMO certainly drive a good portion of the weather. And then there are the strong polar oscilations leading to blocking patterns. The drivers of this seem to be higher in the atmoshpere than just cloud patterns. It’s getting pretty interesting and I am looking forward to see how this symphony plays out.

    A nice explanation from Kirkby.
