Reduced solar activity during the "Little Ice Age" interval from - years ago may be responsible for the "too young" ages during that period. Fluctions in Earth's carbon reservoirs - such as increased burning of fossil fuels - can effect the ratio of 14 C to 12 C in the atmosphere.
The ocean circulates high quantities of ancient carbon deep in the ocean.

Increased rates of deep-water upwelling may responsible for the "too old" radiocarbon ages during the last glaciation. The production of radiocarbon has not varied wildly through time, but the changes produce consistent differences from calander ages. This can be overcome by calibration curves calculated by dating materials of precisely known age. The best samples are tree rings, but annually laminated sediments have also produced excellent results.
Ocean corals, dated by another radiometric method - Uranium-Thorium dating - have also helped to extend the calibration curve beyond the age of the most ancient treering chronologies. Libby had to determine the rate of radiocarbon production to make his first dates. Anthropogenic 14C variations in atmospheric CO2 and wines.
