Unfortunately, humans are on the verge of messing things up. In short, the answer is… sometimes. Human life moves fast, and because the to year ballpark of radiocarbon dating doesn't quite keep up with it, Pearson and collaborators are developing a new radiocarbon method to place floating chronologies in an exact point in time.
However, it should be used with caution. This calibration has been done by compiling a dendrochronological tree-ring record and painstakingly figuring the C14 age of these tree rings. By measuring the ratio of the radio isotope to non-radioactive carbon, the amount of carbon decay can be worked out, thereby giving an age for the specimen in question. Climate records from a Japanese lake are set to improve the accuracy of the dating technique, which could help to shed light on archaeological mysteries such as why Neanderthals became extinct.
