Long-term climate variations and solar effects

• The cosmogenic radionuclides 14C, 10Be and 36Cl allow us to trace solar variability several tens of millennia back in time. Different methods of reconstructing past solar variability based on radionuclide concentrations measured in ice cores will be discussed. The similarity in the variability of measurements of solar magnetic activity and solar irradiance over the last 20 years makes cosmogenic radionuclides a promising tool for reconstructing the variability of solar irradiance in the past. The analysis of many well-dated, high-resolution climate records and comparison with radionuclide records clearly indicates that solar forcing plays an important role in climate change. However, the underlying mechanisms are still a matter of debate and the climate records do not yet show a conclusive picture.
