Whenever I was dragged off to the cinema to see the greatest story ever told I was always surprised when the trailers informed me I was about to disappointed because the real greatest story ever told was actually coming to this theatre soon.
In the realm of Radiocarbon Dating they do it differently because they only promote their B Movie calibration curve.
To produce a curve that can be used to relate calendar years to radiocarbon years, a sequence of securely dated samples is needed which can be tested to determine their radiocarbon age.
The study of tree rings led to the first such sequence: tree rings from individual pieces of wood show characteristic sequences of rings that vary in thickness because of environmental factors such as the amount of rainfall in a given year.
In their wisdom the purveyors of the mainstream calibration curve usually forget about their main feature which is the greatest story ever told by Carbon-14.

This is unfortunate because the 50,000 year History of the World as narrated by Carbon-14 is a really remarkable story with the level of atmospheric Carbon-14 decreasing dramatically between [about] 25,000 BC and [about] 1,000 AD.
Carbon-14 is produced in the upper layers of the troposphere and the stratosphere by thermal neutrons absorbed by nitrogen atoms.
When cosmic rays enter the atmosphere, they undergo various transformations, including the production of neutrons.
These elevated levels of atmospheric Carbon-14 from 25,000 years ago appear to have only been equalled during the period of intense nuclear weapons testing in the early 1960s CE.
The bomb pulse is the sudden increase of Carbon-14 (14C) in the Earth’s atmosphere due to the hundreds of aboveground nuclear bombs tests started in 1945 and intensified between 1950 until 1963 when the Limited Test Ban Treaty was signed by the United States, the Soviet Union and Great Britain.
These hundreds of blasts were followed by a doubling of the concentration of 14C in the atmosphere.
But this interpretation understates the true level of atmospheric Carbon-14 because the 5,730 year half-life of Carbon-14 implies the actual levels of atmospheric Carbon-14 were significantly higher 25,000 years ago [4.36 half-lives ago] and very significantly higher 50,000 years ago [8.73 half-lives ago].
Carbon-12 and carbon-13 are both stable, while the half-life of carbon-14 is 5,730 ± 40 years.
This dramatic decrease in the levels of atmospheric Carbon-14 between [about] 25,000 BC and [about] 1,000 AD suggests the flux of Solar Cosmic Rays entering the Earth’s upper atmosphere has significantly reduced as the Earth’s orbital distance from the Sun has increased.
Overall, the mainstream have been very efficient when it comes to losing low energy Gamma Rays [aka Solar Cosmic Rays] down the back of the sofa.
This interpretation of the historical narrative supports Immanuel Velikovsky’s view that the Earth’s orbital period around the Sun was once “360 days long”.
Numerous evidences are preserved which prove that prior to the year of 365¼ days, the year was only 360 days long.
The texts of the Veda period know a year of only 360 days.
A month of thirty days and a year of 360 days formed the basis of early Hindu chronology used in historical computations.
The ancient Persian year was composed of 360 days or twelve months of thirty days each.
The old Babylonian year was composed of 360 days.
The Assyrian year consisted of 360 days;
The month of the Israelites, from the fifteenth to the eighth century before the present era, was equal to thirty days, and twelve months comprised a year;
The Egyptian year was composed of 360 days before it became 365 by the addition of five days.
Cleobulus, who was counted among the seven sages of ancient Greece, in his famous allegory represents the year as divided into twelve months of thirty days:
The ancient Romans also reckoned 360 days to the year.
the Mayan year consisted of 360 days; later five days were added, and the year was then a tun (360-day period) and five days; every fourth year another day was added to the year.
In ancient South America also the year consisted of 360 days, divided into twelve months.
The calendar of the peoples of China had a year of 360 days divided into twelve months of thirty days each… When the year changed from 360 to 365¼ days, the Chinese added five and a quarter days to their year, calling this additional period Khe-ying;
Worlds In Collision – Immanuel Velikovsky – 1950
Thirty-day months, twelve months, year of 360 days as I put quite a long list, actually, from all ancient calendars, from Incan and from Mayas, from Peru – which [Mayas] means in Mexico – from all ancient European, like ancient Roman and Greek, and also Asian, near Eastern, and Far Eastern civilization.
From each of them I put quotes from authority: twelve months of thirty days, strange as it is, without intercalary.

Additionally, there are clear suggestions in Ptolemy’s Geographia that the annual flux of Solar Cosmic Rays was also once higher in the “habitable world” because a burning zone was [constantly] tilted towards the Sun.
However, the contents and attribution of Ptolemy’s Geographia are troubling.
Firstly, Geographia describes a very limited “habitable world”.
Secondly, this “habitable world” is wedged between burning and freezing zones.
Thirdly, if Ptolemy’s calculations are correct then the Earth used to be about 20 per cent smaller i.e. similar to the 20% inflation implied by the work of Marinus of Tyre.
Fourthly, Ptolemy’s enormous depository of “remarkably accurate” data has “bewildered” scholars.
Clearly, these explanations for the increased levels of atmospheric Carbon-14 between [about] 25,000 BC and [about] 1,000 AD contradict several mainstream narratives that are based upon the Settled Science of Ice Ages and Ice Core Chronologies.
The Last Glacial Maximum (LGM) was the last period in the Earth’s climate history during the last glacial period when ice sheets were at their greatest extension.
Growth of the ice sheets reached their maximum positions in about 24,500 BCE.

Unfortunately, the list of contradicted Settled Science includes Radiocarbon Dating.
So I guess Carbon-14 will remain the greatest story that’s never told…
