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.
