C14 carbon dating accuracy range
The Magnetic Field effects have been superimposed on these values as stated above. We must also assume to know what the ratio of carbon to carbon was in the environment in which our specimen lived during its lifetime. Stonehenge fits the heavens as they were almost four thousand years ago, not as they are today, thereby cross-verifying the C dates.
Living organisms are constantly incorporating this C into their bodies along with other carbon isotopes. Two distinct sediment layers have formed in the lake every summer and winter over tens of thousands of years. Barnes has claimed that the earth's magnetic field is decaying exponentially with a half-life of fourteen hundred years.
Leaves absorb carbon dioxide and oxygen from the air and combine them with the minerals and water from the roots. Our massive consumption of fossil fuels is releasing the carbon which has been locked up in the Earth's crust for the last four or five millennia. The burial of these organisms also meant the burial of the carbon that they contained, leading to formation of our coal, oil and natural gas deposits.
If they are right, this means all C ages greater than two or three thousand years need to be lowered drastically and that the earth can be no older than ten thousand years. One of the most striking examples of different dating methods confirming each other is Stonehenge. One such assumption was that the megalith builders of western Europe learned the idea of megaliths from the Near-Eastern civilizations. All of these effects reduced environmental stress on living creatures, thus allowing larger species to flourish.
Yes, Cook is right that C is forming today faster than it's decaying. The event that triggered the massive geothermal upheaval during Noah's life also made the water vapour canopy unstable.
However, for older samples, the data can only suggest that Sample A is probably older than Sample B, etc. See Renfrew for more details. With further research we may be able to hone the method and increase our confidence in it. The more accurate carbon clock should yield better dates for any overlap of humans and Neanderthals, as well as for determining how climate changes influenced the extinction of Neanderthals.
The surface of the earth was also shielded from the effects of ultraviolet radiation by the water vapour layer, another factor making life easier in the past. She will lead efforts to combine the Lake Suigetsu measurements with marine and cave records to come up with a new standard for carbon dating. The rapid accumulation of radioactive decay end products would give the rocks an appearance of enormous age.
