The Bio Logos Foundation has published a popular-level article by old-earth geologists Gregg Davidson and Ken Wolgemuth presenting arguments for an old earth. One such argument involves counts of sedimentary laminations (“varves”) within the floor of Japan’s Lake Suigetsu. “SG06, A Fully Continuous and Varved Sediment Core from Lake Suigetsu, Japan: Stratigraphy and Potential for Improving the Radiocarbon Calibration Model and Understanding of Late Quaternary Climate Changes.” Quaternary Science Reviews 36: 164–176. Example: analyzing changes in tree growth patterns via tree rings to date a series of landslide events.The science that uses tree rings to date and study past and present changes in glaciers.Archeologists are quickly putting the new knowledge to practical use. In Europe and the Middle East archeologists have started scores of new tree-ring dating projects. C., but with the help of tree rings, the scientists expect to determine the exact years in which its trees were felled. Erupting volcanoes also create dust veils that circle the planet, reducing sunlight and chilling the climate.Tree rings have also provided geologists and climatologists with a new tool for answering some old questions. In North America, this has caused brief periods of frost damage to pine trees, and such damage can be seen in a tree ring representing a single cold year.
Furthermore, Davidson and Wolgemuth made numerous errors in their article (even within their own uniformitarian framework) which cause one to question whether they carefully read all of the technical papers they cited.
See the cal BP discussion for additional information about radiocarbon calibration.
Tree-ring dating works because a tree grows larger--not just height but gains girth--in measurable rings each year in its lifetime.
Example: analyzing ring widths of trees to determine how much rainfall fell per year long before weather records were kept.
