However, the methods must be used with care -- and one should be cautious about investing much confidence in the resulting age...
especially in absence of cross-checks by different methods, or if presented without sufficient information to judge the context in which it was obtained.
Isochron methods avoid the problems which can potentially result from both of the above assumptions.
Isochron dating requires a fourth measurement to be taken, which is the amount of a different isotope of the same element as the daughter product of radioactive decay.
The 1SD error in the mean BP calendar estimate for the VM is 8.5 years.
The 1SD error in the C BP age is 8.5 * 2.77 or 24 years.

In 1946, Libby proposed this groundbreaking idea in the journal Physical Review.All IPCC definitions taken from Climate Change 2007: The Physical Science Basis. CO2 measurements are suspect "The Keeling curve, which is widely used to show the increase in CO2 emissions, is based on data from the top of Mount Mauna Loa in Hawaii.Working Group I Contribution to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, Annex I, Glossary, pp. Mauna Loa is a volcano and it doesn’t seem to me that a volcano is the best place to be taking CO2 measurements" (disinter)The following graph shows atmospheric CO2 levels over the last 10,000 years.Consequently, the trend in Mauna Loa CO2 (1.64 ppm per year) is statistically indistinguishable from the trend in global CO2 levels (1.66 ppm per year).If global CO2 was used in Figure 1 above, the result "hockey stick" shape would be identical.
