The solar activity has been propose as one of the main factors of the climatic variability. Also another type of
processes, the biological ones, have been proposed as important factor in the climatic variation through the
modification of the cloud albedo. In the present work we used the wavelet analysis to investigate the relation
between the polar concentrations of Methane Sulphonic Acid (MSA), that is a product of marine seaweed and total
solar irradiance (TSI) and Beryllium 10, an isotope that forms in the atmosphere and is a proxy of the cosmic
rays. We found that the MSA presents in the 11 years sunspot cycle a negative correlation with the TSI and a
positive correlation with Beryllium-10. Moreover, the Beryllium-10 presents a positive correlation with the MSA at
22 years.
