The climate change, recently commonly referred to global or anthropogenic warming, is extremely important areas of research in recent years. Measurements show that the Earth's mean temperature and mean sea level are rising, mainly due to increasing anthropogenic greenhouse gas emissions, such as carbon dioxide, methane, nitrous oxide, and fluorinated gases. Other important factors of climate change are stratospheric sulfur aerosols, whose ability to reflect solar radiation back to the space may cause cooling effect. These aerosols consist of sulfate particles or sulfuric acid droplets in the atmosphere. Sulfur aerosols have common natural and anthropogenic origin. The volcanos are a major source of particles in the stratosphere, whose concentration depends on the frequency of volcanic eruptions. The lifetime of sulfur aerosols depends on various atmospheric processes – water condensation, rains and winds. These processes are affected by solar cycles and variations of cosmic rays. Here, the variations of volcanic sulfate since 1600 are compared with solar indices in different narrow frequency bands with interannual, decadal and centennial periods. Possible solar influence on volcanic sulfate is investigated by common cycles of solar and Earth data. The solar data consist of centennial time series of Total Solar Irradiance (TSI) and Sun Spot Numbers (SSN). The Earth data are represented by millennial data of the volcanic sulfate record in the Greenland ice core. Relatively good agreement is discovered between some interannual, decadal and centennial cycles of volcanic sulfate and solar indices.
