Recent research on seasonal effects on tree rings in other trees in the same genus, the plantation pine , has revealed that up to five rings per year can be produced and extra rings are often indistinguishable, even under the microscope, from annual rings.
It is also worth noting that the half-life used in carbon dating calculations is 5568 years, the value worked out by chemist Willard Libby, and not the more accurate value of 5730 years, which is known as the Cambridge half-life.
Although it is less accurate, the Libby half-life was retained to avoid inconsistencies or errors when comparing carbon-14 test results that were produced before and after the Cambridge half-life was derived.
In 1859, the German-American Jacob Kuechler (1823–1893) used crossdating to examine oaks (Quercus stellata) in order to study the record of climate in western Texas.
During the first half of the 20th century, the astronomer A. Douglass founded the Laboratory of Tree-Ring Research at the University of Arizona.
Results of carbon-14 dating are reported in radiocarbon years, and calibration is needed to convert radiocarbon years into calendar years.
Uncalibrated radiocarbon measurements are usually reported in years BP where 0 (zero) BP is defined as AD 1950.
However, when the interpretation of scientific data contradicts the true history of the world as revealed in the Bible, then it’s the interpretation of the data that is at fault.
It’s important to remember that we have limited data, and new discoveries have often overturned previous ‘hard facts’.
This procedure depends on temporal placement of fragments of wood using carbon-14 (C age and that also extends to a younger age.
A tree ring pattern that matches is found close to where the carbon ‘dates’ are the same. It assumes that it is approximately correct to linearly extrapolate the carbon ‘clock’ backwards. The closer one gets back to the Flood the more inaccurate the linear extrapolation of the carbon ‘clock’ would become, perhaps radically so.
BP stands for “Before Present” or “Before Physics” as some would refer to it.
