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).The study found that water temperatures increased on average by 0.23ºF (0.13ºC) per decade between 19, while air temperatures cooled by 0.02 to 0.09ºF (0.01 to 0.06ºC) per decade during the same period. examined the locations of 1,007 of the 1,221 monitoring stations used to determine average surface temperature changes across the continental United States.The paper found that 92% of these stations are positioned in sites that can cause errors of 1.8ºF (1ºC) or more.  For example, some stations are located over asphalt (making them hotter at certain times), and others are located in partial shade (making them cooler at certain times).Our identification strategy builds on the comparison of outcomes between plants subject to the full tax and plants that paid only 20% of the tax.Exploiting exogenous variation in eligibility for the tax discount, we find that the carbon tax had a strong negative impact on energy intensity and electricity use.
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.Creationists have shown that the biblical kind is usually larger than the ‘species’ and in many cases even larger than the ’genus’—see my article Ligers and wholphins? Taking this into account would bring the age of the oldest living Bristlecone Pine into the post-Flood era.Claimed older tree ring chronologies depend on the cross-matching of tree ring patterns of pieces of dead wood found near living trees.) of the White Mountains of Eastern California, were dated in 1957 by counting tree rings at 4,723 years old.This would mean they pre-dated the Flood which occurred around 4,350 years ago, taking a straightforward approach to Biblical chronology.
