By carbon dating a piece of wood which has also been dated by counting its annual tree-rings, scientists can create a table by which they can convert the questionable Carbon-14 years into true calendar years.

This is how it works: scientists begin with a living tree or dead wood specimen which can be accurately dated by some reliable means.

And finally, they count all of the tree-rings, using the matching patterns to connect all the pieces, and they determine the age of the oldest piece of wood.

This is called a "long chronology." By dating the oldest piece of wood using the Carbon dating method and comparing the two dates, scientists can make the necessary adjustments to their calculations. Aardsma, "Myths Regarding Radiocarbon Dating," Impact, No.

Unfortunately, this method of calibrating Carbon dating by using tree-ring dating is itself flawed. 189, March 1989.) Carbon Dating - What Do The Experts Think?

Then they look for pieces of dead wood which are older than the specimen which they started with and whose tree-ring patterns match up with and overlap those of the first specimen (tree-rings can vary greatly in width due to environmental factors and thus produce a pattern by which we can match specimens which grew in the same environment).Scientists then look for more pieces of dead wood to match and overlap the second specimen and on and on.Advocates of the Carbon dating method have turned to "Dendrochronology" (a.k.a.tree-ring dating) to calibrate their timescale (that is, to adjust it to compensate for the C-12 to C-14 ratio fluctuations).

Carbon Dating - Dendrochronology As we've already seen, in order for Carbon dating to work we need to know what the C-12 to C-14 ratio was at the time of a specimen's death.

If the ratio has fluctuated throughout the unobservable past (and we can be sure that it has), how can we determine what the ratio was during the lifetime of a specimen that lived and died before we first began measuring the ratio?
