An accurate chronometer that covers the past 50,000 years is of paramount importance in fields such as geophysics, geochemistry, and paleoclimatology. However, we now recognize that the atmospheric 14C/12C ratio varies with time, which affects the accuracy of this geochronometer. Fortunately, short and long-term 14C variations on Earth and provide invaluable insights on climatological, biogeochemical, geophysical and astrophysical processes.
