This is huge. Consider this key sentence: “The (climate) forcing from changes in total solar irradiance alone does not seem to account for these observations, implying the existence of an amplifying mechanism such as the hypothesized GCR-cloud link.” In other words, an admission that there’s likely a solar role in climate beyond direct heating from the sun, such as Svensmark’s theory about the relation between the solar wind, cosmic rays, and cloud formation. This should be a body blow to the man-caused global warming crowd. Do read the whole thing.
