Description:
Abstract:
Data set consists of reconstructed solar irradiance data and cosmogenic nuclide production (10Be and 14C) from an ice core at the South Pole (Raisbeck 1990). Based on a quantitative study of the common fluctuations of 14C and 10Be production rates, we have derived a time series of the solar magnetic variability over the last 1200 years. This record is converted into irradiance variations by linear scaling based on previous studies of sun-like stars and of the Sun's behavior over the last few centuries. The new solar irradiance record exhibits low values during the well-known solar minima centered about 1900, 1810 (Dalton), and 1690 AD (Maunder). Further back in time, a rather long period between 1450 and 1750 AD is characterized by low irradiance values. A shorter period is centered about 1200 AD, with irradiance slightly higher or similar to present day values. It is tempting to correlate these periods with the so-called "little ice age" and "medieval warm period", respectively. An accurate quantification of the climatic impact of this new irradiance record requires the use of coupled atmosphere-ocean general circulation models (GCMs). Nevertheless, our record is already compatible with a global cooling of about 0.5 - 1 C during the "little ice age", and with a general cooling trend during the past millennium followed by global warming during the 20th century (Mann et al. 1999).
