Forgive me if this was mentioned by someone else earlier. There is now an updated “tree-ring, varve, carbon-14” paper based on a whole new round of C14 measurements in Lake Suigetsu. The paper includes a step-by-step demonstration of why we can be confident in the conventional understanding of tree-ring growth, varve formation, and carbon-14 production and decay. The paper also includes descriptions of the methods YEC employ for the purpose of creating doubt. The paper will become open access to non-ASA members after January. If you aren’t a member, or don’t know a member, you can email me at davidson@olemiss.edu and I can send you a pdf (please do not post it or send it to friends before January).
