The steady state concentration of cosmogenic ¹⁴C in the atmospheric carbon dioxide has decreased over the past 6,000 years by almost 10%. This decrease is commonly attributed to an increase in the geomagnetic dipole moment by as much as a factor of three. Superimposed upon this decrease are fluctuations of the atmospheric ¹⁴CO₂ radioactivity with a time constant on the order of some 100 years. These relatively rapid fluctuations are caused by variations in the ¹⁴C production due to the heliomagnetic modulation of the galactic cosmic rays that lead to the production of ¹⁴C in the atmosphere. The purpose of this research in climate dynamics is to find ¹⁴C values further back in time and find an explanation for the divergence between ¹⁴C dates and true values.
