false, the Sun and insolation drives climate and climate change, greenhouse gas effects are secondary
Invalid, that does not contradict TFS or TFA. The point being made is not that solar activity is a minor influence, but that that changes in solar isolation cannot account for the patterns of climate change over the last millennium in the northern hemisphere, and that effects of volcanism and greenhouse gases fit the data better.
