 But if you look at the error bars, there's actually a formal disagreement between the radiocarbon ages and the varve ages. But because of the way that Davidson and Wolgamath plotted this on their graph, that important fact was obscured. There's some other problems. For one thing, they seem to have mistaken a radiocarbon calibration curve for actual data. There's some other mistakes in there as well. But the bottom line is when you look at the details of this argument, this paper is not nearly as formidable.
