At least to the uninitiated, carbon dating is generally assumed to be a sure-fire way to predict the age of any organism that once lived on our planet.

Some believe trees are known to be as old as 9,000 years. A lot of people doubt this claim for various good reasons I wont go into here.

Since 1947, scientists have reckoned the ages of many old objects by measuring the amounts of radioactive carbon they contain.

New research shows, however, that some estimates based on carbon may have erred by thousands of years.

The technology uses a series of mathematical calculations—the most recognizable of which is known as half-life—to estimate the age the organism stopped ingesting the isotope.

Unfortunately, the amount of Carbon-14 in the atmosphere has not been steady throughout history.

Specifically, there are two types of carbon found in organic materials: carbon 12 (C-12) and carbon 14 (C-14).

It is imperative to remember that the material must have been alive at one point to absorb the carbon, meaning that carbon dating of rocks or other inorganic objects is nothing more than inaccurate guesswork.In fact, it has fluctuated a great deal over the years.This variation is caused by both natural processes and human activity.Dates up to this point in history are well documented for C14 calibration.For object over 4,000 years old the method becomes very unreliable for the following reason: Objects older then 4,000 years run into a problem in that there are few if any known artifacts to be used as the standard.Libby, the discoverer of the C14 dating method, was very disappointed with this problem.
