Children around the world know that to tell how old a tree is, you count its rings [sic]. ... In her captivating new book, Tree Story, Valerie Trouet reveals how the seemingly simple and relatively familiar concept of counting tree rings has inspired far-reaching scientific breakthroughs that illuminate the complex interactions between nature and people.1
Once you look at trees through the eyes of a dendrochronologist, you never quite see the leafy wonders the same way again. Peel away the hard, rough bark and there is a living document, history recorded in rings of wood cells. Each tree ring pattern of growth is unique, as the width of a ring depends on how much water was available that year.2
Trees possess a series of rings that correspond to annual cycles of growth, which are determined by atmospheric and climatic events. To the untrained eye, the rings of a favourite garden tree stump might elicit nothing other than childhood memories of laboriously counting. … [For example] there is Methuselah, the 4,789-year-old [sic] sage of the Ancient Bristlecone Pine Forest; and countless other trees which have stood witness to the events in our history books.3

But wait—how can a living tree be 4,789 years old? If that age calculation is precisely accurate, and is compared to the Bible’s chronology data, then would that mean this Methuselah tree somehow survived Noah’s Flood?4
No eyewitness told us the Methuselah tree’s age, so this conclusion about the no-longer-observable past must be based on some other age-counting method—and it was.5 The age was assumed based upon tree ring growth, relying upon the assumption of “annual growth ring” uniformity, which is critical to the secular dendrochronologist’s version of uniformitarianism.
The big assumption here is that tree rings are “annual” (yearly)—each identifiably distinct ring is deemed a year of growth. Thicker rings are assumed to represent rain-abundant years; thinner rings are supposed to show years of less rainfall.
And so those who review or promote Trouet’s Tree Story repeat the same story, that tree rings are annual growth indicators.1-3 But is this an outdated error? Should up-to-date tree scientists, and elite academic institutions like Johns Hopkins University, be popularizing the annual-growth-ring concept?
No, says Dr. John Morris, who reports on tree growth research by Dr. Geoff Downes, a veteran tree physiologist and dendrochronologist.
The giant sequoia trees of California are known to live over 3,000 years, discerned through tree ring dating. Under normal circumstances, woody trees add one ring per year. A ring typically consists of a light-colored growth portion and a dark-colored portion produced in a stabilization season. However, some trees do not produce annual rings at all, especially those in temperate or tropical regions.6
Of course, trees don’t talk to humans—so trees can’t report which years it didn’t produce any growth rings.
Likewise, no tree can tell you which years had on-and-off weather conditions that facilitated growing multiple growth rings within one year.7
In other words, how would you know which years are exceptional, and thus are not represented by exactly one growth ring?
But how valid is the assumption of one ring per year in a climate where tree-growing conditions are variable? That very assumption is regularly put to the test by research foresters. They investigate how a tree grows, how and when it adds a new ring, effect of nutrients, rainfall, etc., over a range of related conditions. … Researchers monitor tree growth by attaching sensitive probes onto and into actively growing trees. Measurements are sometimes taken every fifteen minutes throughout the years of study! These are not mere ring-counting efforts on living and dead trees, but an observation of living trees and how they react to ambient conditions—how and when they make a ring.6
And what is the result of all these long-timeframe studies on growing trees, where weather factors are artificially varied as experiments?
It has been found that all trees, even slow-growing ones, respond dynamically to tiny environmental changes, even hourly changes in growing conditions. Scientists have observed that numerous “normal” conditions can produce an extra ring or no ring at all. Weather was fingered as the most “guilty” culprit. Unusual storms with abundant rainfall interspersed with dry periods can produce multiple rings, essentially one per major storm. Thus, the basic assumption of tree ring dating is demonstrably in error.6
Ironically, the weather patterns immediately after the Genesis Flood were anything but uniform when compared to our normal climate patterns. That would make quite a difference in growth ring production in trees that germinated in the centuries immediately following the Flood.6,7
Remember that the centuries immediately following the Flood witnessed the coming of the Ice Age. … The still-warm oceans rapidly evaporated seawater, thus providing the raw material for major monsoonal-type storms. Earth was ravaged by frequent and wide-ranging atmospheric disturbances, dumping excessive snowfall in northern regions and rainfall to the south. If ever there was a time when multiple rings could develop in trees, this was it. Those centuries probably produced tree ring growth that was anything but annual. Thus, far from disproving biblical history, tree ring studies provide supportive and instructive information about true history.6
So, children can expect to be taught that tree rings are uniformly grown, and that a tree’s true age can be reliably measured by treating each growth ring as indicating a new “year” of life, like counting birthdays.
This is another example of evolutionists using empirical science methods (with a uniformitarian assumption) as they try to reconstruct unique events of the past. They do this apart from adequate reliance upon forensic science evidence standards—such as using observations of eyewitness-report-based records, corroborated (or refuted) by physical evidence that can be seen in the present.5
Lamentably, to those with evolutionary blind-spots, the big-picture forest seems to get lost among the trees.

7. When more than one growth ring occurs within a year, the “extra” rings are called a fancy name: intra-annual density fluctuations (or IADFs)—nicknamed “false rings” or “double rings.” This amounts to a verbal dodge to avoid admitting that multiple growth rings can occur within a year, so simply counting growth rings cannot guarantee a correct count of a tree’s age.
