UV Radiation - One of the Climate Drivers?

The evidence is piling up that clouds have a major effect on the climate, and that low cloud formation is correlated with cooler temperatures.  The SKY and CLOUD experiments are revealing the role of solar activity and cosmic rays:

<p>First of all, the reported findings by Joanna Haigh et all <a href="http://www.nature.com/news/2010/101006/full/news.2010.519.html" title="http://www.nature.com/news/2010/101006/full/news.2010.519.html">http://www.nature.com/news/2010/101006/full/news.2010.519.html</a> are absolutely correct on the basis of my experimental findings. Fig.1 of their paper showing UV dominant optical emission from Sun matches with the UV dominant optical emission observed from radioisotopes and XRF sources shown in Fig.1 of my peer reviewed paper: UV dominant optical emission newly detected from radioisotopes and XRF sources, Brazilian Journal of Physics, vol. 40, no. 1, March 2010, <a href="http://www.sbfisica.org.br/bjp/files/v40_38.pdf" title="http://www.sbfisica.org.br/bjp/files/v40_38.pdf">http://www.sbfisica.org.br/bjp/files/v40_38.pdf</a> . This suggests that UV dominant Sun light could be reproduced at laboratory level from radioisotopes and XRF sources. Most likely, radioisotopes produced by Uranium fission powers the Sun light. Astrophysicists were highly successful in detecting both Solar X-rays and UV or EUV. Now, the previously unknown atomic phenomenon described in my paper explains how solar gamma, beta, XRF emissions causes UV dominant optical emission. When solar cycle is at its maximum with maximum sun spots, solar x-ray emission, EUV and UV reach maximum 83 to 96% from a wide range of radioisotopes having different ionizing radiation energies and half lives produced by uranium fission taking place at different sites on the Sun’s surface. The solar X-rays can most likely be the XRF from radioisotopes dominant in XRF emission such as 113-Sn (In X-rays), 152-Eu (Sm X-rays), and 201-Tl (Hg X-rays) and due to knocking out many of the core electrons. All low energies not only X-rays but also gamma, and beta contribute to solar UV as much as 96% in the gross light intensity (Fig.3, BJP, 2010). That is why solar UV reaches maximum, and visible and near infrared radiations remain very low at around 4% in the gross light intensity, when solar cycle is at its maximum. Maximum solar UV seems to be responsible for lowering of temperatures as we approach North and South poles. My experimental study provides the key why Sun emits an amount of ultraviolet radiation in the spectrum four to six times smaller than that predicted by the empirical model, but an increase in radiation in the visible wavelength during waning period of the solar cycle, and why low solar UV warms the Earth's atmosphere. Sun provides us constant source of light, because radioisotopes which emit low energies whether gamma, beta or X-ray but having long half life maintain UV to be between 83-96%, while VIS and NIR radiations share the rest of percent light. During Sun’s waning period, the 96% UV slowly falls to 83% with the decay of short lived radioisotopes and long lived radioisotopes like 60-Co, 90-Sr remains at the spot of fission (Sun spots). In general, the 16% fall in UV reported by some researchers closely agrees with the 13% variation noticed in UV with the radioisotopes tested by me. For instance 131-I, with 8.0197 days half life decays to insignificant levels after ten half lives that means 80 days. Its predominant energy 0.6065 MeV (β) causes maximum UV (96.64%), while 3.22% VIS, and 0.14% NIR radiation intensities remain low in the gross light intensity (Table 1, Braz. J. P, March 2010). In comparison, 90-Sr undergoes slow decay with long half life of 28.8 years and continue to produce 90-Y (half life: 64 hours) until reaches insignificant levels after 288 years. The UV noticed to be maximum (96.64%) from 131-I caused by 0.6065 MeV energy dipped to 83.36% caused by 2.288 MeV energy of β from 90-Y, but VIS, and NIR radiation intensities raised to 8.02% and 8.62% respectively in the gross light intensity. Fall in UV and rise in VIS and NIR radiations from radioisotopes such as 90-Sr + 90-Y with long half life and strong ionizing energy that remain at the site of Uranium fission or as fallout on Sun’s surface explains the fall in UV and rise in VIS NIR radiation levels observed during Sun’s waning period by Joanna Haigh et all. Notably. the UV, visible (VIS), and near infrared (NIR) radiations also result from fission fragments (radioisotopes) reaching the Earth, by the atomic phenomenon described in my paper. The raise in near infrared (NIR) radiation caused by hard gamma, and beta emissions from long lived fission products such as 90-Sr + 90-Y warms the Earth's atmosphere.</p>

Hi Geoff, first time I've commented although I'm a daily visitor, so first things first. Geoff I have a great deal of confidence that you bring authenticity and conviction without bias to this science. I applaud your credits to it's predecessors whose input you regularly assign virtue. I would be most interested to discuss atmospheric dynamics with you and ask whether, if you are interested you would like this here or on another part of your site or if you would care to contact me directly first. I do believe that the solar dynamics and it's periodic variability control world climate. As an individual I am trying to piece together the true science of atmospheric response to solar energy.
