We "know" this has to be wrong as it uses temperature reconstructions of Micheal Mann as evidence of the correllation between temperature and sunspot activity. Right? http://cc.oulu.fi/~usoskin/personal/Sol ... lished.pdf The current high level of solar activity may also have an impact on the terrestrial climate. We note a general similarity between our long-term SN reconstruction and different reconstructions of temperature [28,29]: (1) both SN and temperature show a slow decreasing trend just prior to 1900, followed by a steep rise that is unprecedented during the last millenium; (2) great minima in the SN data are accompanied by cool periods while the generally higher levels of solar activity between about 1100 and 1300 correspond to a relatively higher temperature (the medieval warm period) [30].

Didn't the CERN experiments already show this effect, which also showed the nuclei were too few and too small to have the impact observed in the atmosphere? As I said, there is LESS evidence of the hypothesis you claim is more probable. http://science.au.dk/en/news-and-events ... skydaekke/ Facts about the experiment A chamber contains air with precisely balanced amounts of sulphur dioxide, ozone and water vapour irradiated with electrons. Sunlight is a necessary ingredient for aerosol formation in the natural atmosphere, and it is imitated in the climate chamber by a lamp that emits ultraviolet light. Natural atmospheric processes such as the formation of sulphuric acid are thus imitated, and these are an important ingredient in the aerosols. When electrons from the accelerator irradiate the air mixture, an increase takes place in the production of aerosols, which act as nuclei for the production of cloud droplets. In previous SKY experiments conducted by DTU Space in Copenhagen, cosmic radiation was simulated by gamma radiation, and the scientists saw here that the gamma rays could also form aerosols. In the new experiment with the energy-rich electrons from the ASTRID accelerator, there is much more resemblance to the cosmic rays that occur in nature. |
