re: #323 Cineaste

My understanding of Svensmark’s theory, which I am by no means an expert on, is that it relies on all forms of cosmic radiation, not just deep-space cosmic radiation. The predominant cosmic radiation we receive is from the Sun and the amount of radiation hitting the earth over the past six decades diverges from the expected results of Svensmark’s theory. The earth has gotten warmer and yet there has been no noticeable increase in cosmic radiation (solar or otherwise). Am I incorrect on this one?

The cosmic rays that Svensmark is concerned with come from deep space (e.g. from novas). The idea is that the solar flux deflects these cosmic rays (which affect cloud formation). Less solar flux means more low clouds and that may lead to cooling.
