In addition to being crucial to the establishment of archaeological chronologies, radiocarbon dating is vital to the establishment of time lines for many Holocene and late Pleistocene palaeoclimatic studies and palaeoenvironmental reconstructions.

The calibration curves necessary to map radiocarbon to calendar ages were originally estimated using only measurements on known age tree-rings.

There have been several versions of the calibration curve, beginning, I think, in 1986 with Stuiver and Kra (1986).

The current version of the calibration curve is Int Cal13.

Radiocarbon dates need calibrating because the relationship between calendar age and radiocarbon age is non-linear.

People wonder how millions of years could be squeezed into the biblical account of history. Christians, by definition, take the statements of Jesus Christ seriously.Working with several collaboraters, Libby established the natural occurrence of radiocarbon by detecting its radioactivity in methane from the Baltimore sewer.In contrast, methane made from petroleum products had no measurable radioactivity.Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering—the reason Jesus came into the world (See Six Days? He said, This only makes sense with a time-line beginning with the creation week thousands of years ago.It makes no sense at all if man appeared at the end of billions of years.In a stratigraphical context objects closer to the surface are more recent in time relative to items deeper in the ground.
