Abstract: This talk will review some of the observational evidence for an influence of solar activity on the climate of the lower atmosphere and discuss mechanisms which might be responsible. During the most recent solar cycle minimum (2008-9) the Sun was in a state of very low activity and its ongoing behaviour suggests that the next maximum will be of low amplitude. Further, some satellite measurements have suggested that the solar spectrum has been behaving in a strange and unexpected way. The implications of different spectra for radiative forcing and for climate effects through stratosphere-troposphere coupling will be discussed.
