Carbon dating does not work

(This, in turn, is caused by variations in the magnetic fields of the earth and sun, for example.) Although the ratio of radiocarbon to stable carbon in the atmosphere has varied over time, it is quite uniform around the globe at any given time because the atmosphere mixes very quickly and constantly.Plants obtain all their carbon atoms from the atmosphere.The ratio of radiocarbon to stable carbon atoms in the atmosphere has varied in the past.This is because the amount and strength of cosmic radiation entering the earth's atmosphere has varied over time.The raw radiocarbon date of any sample can then be converted to true date by using this calibration table.

However, cosmic radiation constantly collides with atoms in the upper atmosphere.When an organism dies (whether plant or animal) its intake of carbon atoms ceases.The starting ratio of radiocarbon to stable carbon is locked in at that point. The purpose in each of these methods is to determine the ratio of radiocarbon to stable carbon in the sample.Thus the ratio of radiocarbon to stable carbon in living animal tissue is also virtually the same as the ratio of radiocarbon to stable carbon in the atmosphere at any given time.This ratio is the same for all organisms across the globe at a given time due to the mixing of the atmosphere mentioned above.

This tendency to decay, called radioactivity, is what gives radiocarbon the name radiocarbon.
