Hot Nude How do they know carbon dating is accurate.

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. The authors measured a series of carbon ages in southern Jordan tree rings, with established calendar dates between and A.

They found that contemporary plant material growing in the southern Levant shows an average offset in radiocarbon age of about 19 years compared the current Northern Hemisphere standard calibration curve.
