Natural ratio Radiocarbon dating is a 70-year-old technique now used with increasing precision to date anything once alive from the last 50,000 years.

It exploits the natural ratio of two isotopes of carbon in the atmosphere.

That means that a freshly-dead dung beetle that falls into an Egyptian tomb dating from the reign of Cleopatra would have the same radiocarbon age as the scarab that was trapped in the tomb under the sarcophagus 20 centuries ago.

“Given current emissions trends, fossil fuel emission-driven artificial ‘aging’ of the atmosphere is likely to occur much faster and with a larger magnitude than previously expected,” Graven concludes.
