This is because pre-modern carbon 14 chronologies rely on standardised northern and southern hemisphere calibration curves to determine specific dates and are based on the assumption that carbon 14 levels are similar and stable across both hemispheres.

If this is true, then many of our established historical timelines are thrown into question, potentially needing a re-write of the history books.

In a paper published to the , the team led by archaeologist Stuart Manning identified variations in the carbon 14 cycle at certain periods of time throwing off timelines by as much as 20 years.

“There has been much debate for several decades among scholars arguing for different chronologies sometimes only decades to a century apart, each with major historical implications.

And yet these studies […] may all be inaccurate since they are using the wrong radiocarbon information,” Manning said.
