The extended tree ring chronologies are far from absolute, in spite of the popular hype.To illustrate this we only have to consider the publication and subsequent withdrawal of two European tree-ring chronologies.

They live in all sorts of conditions too: in temperate and tropical areas and in arid locations, from mountain landscapes to the rainforests of the equator and the temperate uplands of Scandinavia, they are everywhere.

They are used for decoration in parks and gardens all over the world.

Wood is a solid and strong material as we all know, valued for its longevity and strength.

Each season of growth (typically annual but not always, we will examine this problem later) a new ring is set down in the body of the tree.

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.

As a tree physiologist I would say that evidence of false rings in surely counts much more strongly against such the notion. Considering that the immediate post-Flood world would have been wetter with less contrasting seasons until the Ice Age waned (see Q&A: Ice Age), many extra growth rings would have been produced in the Bristlecone pines (even though extra rings are not produced today because of the seasonal extremes).Before this, their ancestors would have a recognisable tree form, believed to be that of a giant type of fern that began the process of developing a woody stem.Wood helps the developing tree to stay strong as it gets older and grows upwards, building new branches and drinking in more sunlight for photosynthesis reproduction.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.Most people who enter into studying tree rings typically come from one of several disciplines: Though dendrochronology also has uses for art historians, medieval studies graduates, classicists, ancient and historians due to the necessity to date some of the materials that the fields will be handling in their research projects.
