The problems with carbon dating

These variations, or offsets, of up to 20 years in the calibration of precise radiocarbon dating could be related to climatic conditions. Pre-modern radiocarbon chronologies rely on standardized Northern and Southern Hemisphere calibration curves to obtain calendar dates from organic material.

These standard calibration curves assume that at any given time radiocarbon levels are similar and stable everywhere across each hemisphere. So we wondered whether the radiocarbon levels relevant to dating organic material might also vary for different areas and whether this might affect archaeological dating.

Cosmic rays and changes in Earth's climate can cause irregularities in the amount of. One of the most essential tools for determining an ancient object's age, carbon dating, might not be as accurate as we once thought.
