is a technique used by scientists to learn the ages of biological specimens – for example, wooden archaeological artifacts or ancient human remains – from the distant past. It can be used on objects as old as about 62, years. Radiocarbon dating is a method for determining the age of an object containing organic Willard Libby, who was then at Berkeley, learned of Korff's research and conceived the idea that it might be possible to use radiocarbon for dating.
Some speculated that such irregularities might be caused by variations in the Earth's magnetic field. A stronger field would tend to shield the planet from particles from the Sun, diverting them before they could reach the atmosphere to create carbon Another possibility was that the cause lay in the Sun itself.
Tracking carbon also proved highly useful in historical and contemporary studies of the global carbon budget, including the movement of carbon in the oceans and its complex travels within living ecosystems.
