No competent scientists denies the link between solar output and
climate. They all (we all) appreciate that multiple factors affect the
climate system. A fair reading of the literature leads to this
conclusion, (quoted from Solanski, S.K. 2002. Solar variability and
climate change: is there a link? Astronomy & Geophysics 43(5): 9-13):
"... Obviously, prior to roughly 1980 the solar irradiance on the whole
ran parallel to and even slightly ahead of the Earth's tmeperature.
"This is consistent with a causal relationship between the two and
supports, but by no means proves, the view that the sun has had an
important, possibly even dominant influence on our climate in the past.
Other contributors to climate variability are volcanic activity, the
internal variability of the Earth's atmosphere and man-made greenhouse
gases. After 1980, however, the Earth's temperature exhibits a
remarkably steep rise, while the Sun's irradiance displays at the most a
weak secular trend. Hence the Sun cannot be the dominant source of this
latest temperature increase, with man-made greenhouse gases being the
likely dominant alternative."
