The data on the 14C concentration in the Earth’s atmosphere are studied on a time span of 50000 years. It is shown that the Hallstatt cycle (a temporal variation with a period of 1500–2000 years) has been present in this series for at least 30000 years. However, this cycle is not purely of solar origin; nonsolar (supposedly climatic) factors contribute into it in certain epochs.
