Imagine a large swimming pool into which one drop of red ink falls each year. The water dilutes the ink so much that even after a few thousand years very little pinkness can be seen in the pool.

Answers to Creationist Attacks on Carbon Dating | National Center for Science Education

Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material. But new research shows that commonly accepted radiocarbon dating standards can miss the mark—calling into question historical timelines. Archaeologist Sturt Manning and colleagues have revealed variations in the radiocarbon cycle at certain periods of time, affecting frequently cited standards used in archaeological and historical research relevant to the southern Levant region, which includes Israel, southern Jordan and Egypt. 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.

Is Carbon Dating Accurate?

A common misconception about radiocarbon dating is that it gives a precise date B. In actual practice radiocarbon dating can only give a range of dates for a given sample to B. The precision of a radiocarbon date tells how narrow the range of dates is. There are two main factors which determine the precision of a radiocarbon date. Modern accelerator mass spectrometry used for radiocarbon dating purposes to separate radiocarbon atoms from stable carbon atoms and count them is quite precise.
