Problems with tree ring dating

Any analysis that does not employ rigorous, replicable crossdating is not dendrochronological [tree-ring dating] in nature: counting rings does not afford the comparative validation necessary to produce absolutely dated ring sequences.” Thus, one cannot build reliable chronologies simply from counting tree rings. For example, “unfortunately, the low-elevation Huon pine[s] do not crossdate well and the ring-width chronologies that have been developed show a complex but weak temperature signal.” In other words, forest scientists sometimes have difficulty figuring out which ring features correspond to which temperature range or calendar year.And some tree rings are quite faint: “The ring that marked the change could not be dated directly in each core because some rings, especially those near the outer part of the trunk, are indistinct.” And ring growth appears to be inconsistent: “Sometimes tropical trees that show cambial increment [woody growth] during each month of the year produce multiple growth rings, emphasizing the uneven utilization of carbohydrates.” But are growth rings consistently annual in temperate climates?This page does not attempt to cover the details of wood formation that make tree rings possible, but rather provides an overview of common wood characteristics and anomalies that you will need to identify when you are crossdating.Variation in these rings is due to variation in environmental conditions when they were formed.

Dormancy of this type is classified as temporary, as it lasts a few days or a few weeks.” Instead of calling it a “false ring,” maybe they should have called it a “false year.” Understanding that climate and other changes cause trees to produce more rings than the number of years they’ve been growing reconciles tree rings with biblical history.And given the wild climate swings since the Ice Age, there is every reason to expect extra rings in trees that began growing soon after the Flood.To understand this process we must first understand a little bit about the atoms themselves and how they get their names.Notice in the diagram that eight different isotopes of Carbon are illustrated.Three of the Carbon isotopes (C) are found in nature.
