Problems with carbon dating 14

Since , 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. It is too soon to know whether the discovery will seriously upset the estimated dates of events like the arrival of human beings in the Western Hemisphere, scientists said. But it is already clear that the carbon method of dating will have to be recalibrated and corrected in some cases.

What the Drawbacks are to Carbon14 Dating

CALGARY — A partner in an Alberta carbon capture and storage project that recently celebrated storing its one millionth tonne of CO2 says it has an agreement with a northwestern Alberta chemical plant developer that could result in building a second large-scale system. Privately held Enhance Energy Inc. Currently, Enhance's partner Wolf Midstream captures CO2 from two industrial plants northeast of Edmonton and transports them south on the kilometre Alberta Carbon Trunk Line system to be injected underground in an Enhance Energy oilfield for improved oil recovery and permanent storage. Adding the carbon capture component is essential to attract financial backers for his company's proposed plant because it will enable its production to be net carbon emission neutral and thus considered "blue methanol," said Nauticol CEO and co-founder Mark Tonner.

Radiocarbon dating is one of the best known archaeological dating techniques available to scientists, and the many people in the general public have at least heard of it. But there are many misconceptions about how radiocarbon works and how reliable a technique it is. Radiocarbon dating was invented in the s by the American chemist Willard F. Libby and a few of his students at the University of Chicago: in , he won a Nobel Prize in Chemistry for the invention. It was the first absolute scientific method ever invented: that is to say, the technique was the first to allow a researcher to determine how long ago an organic object died, whether it is in context or not.
