When dating wood there is no such problem because wood gets its carbon straight from the air, complete with a full dose of C-14.

The creationists who quote Kieth and Anderson never tell you this, however.

Admittedly, this old wood comes from trees that have been dead for hundreds of years, but you don't have to have an 8,200-year-old bristlecone pine tree alive today to validly determine that sort of date.Question: But don't trees sometimes produce more than one growth ring per year? Answer: If anything, the tree-ring sequence suffers far more from missing rings than from double rings.This means that the tree-ring dates would be slightly too young, not too old.In the growth-ring analyses of approximately one thousand trees in the White Mountains, we have, in fact, found no more than three or four occurrences of even incipient multiple growth layers. 840) In years of severe drought, a bristlecone pine may fail to grow a complete ring all the way around its perimeter; we may find the ring if we bore into the tree from one angle, but not from another.Hence at least some of the missing rings can be found.Carbon from these sources is very low in C-14 because these sources are so old and have not been mixed with fresh carbon from the air.
