Solar Variability and Climate - Joint ProClim- / ISSI Forum
2 July 1999 in Bern
During the last years the discussion about the influence of solar variability on climate change has been intensified. Since a long time it is known that variations of solar radiation influence the temperature on the earth's surface. However, since the direct effect by known physical processes is much smaller than the observed changes, this topic received only little scientific attention. As a consequence the Second Assessment Report of the IPCC handled the topic with less care than probably would have been necessary.
