Activity is quiet on the sunspot front ... - On Line Opinion - 29/8/2008

With the sun being quiet for a surprisingly long time, plenty of commentators are pointing to the possibility of a Maunder Minimum - a period from 1645 to 1715 with very few sunspots which is associated with a series of bitter winters known as the Little Ice Age. Although it is widely acknowledged that there must be some link between the sun’s activity and climate, the nature of the link and its effectiveness is hotly debated. The IPCC models, the ruling orthodoxy, gives star billing to the effect of industrial gases in the atmosphere and places solar variations in the also ran category. However, as we shall see those models have proved largely useless for forecasting - in the short term, at least - and there are no rival climate theories. The sceptics largely decline to forecast, pointing out, with some justification as it turns out, that there is as yet no means of forecasting what the sun will do.
