Radiometric dating, or radioactive dating as it is sometimes called, is a method used to date rocks and other objects based on the known decay rate of radioactive isotopes.Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials.Fossil-fuel emissions are not only messing with our future, but they are also messing with our ability to accurately date the past.A new study has found that fossil-fuel emissions could impact radiocarbon dating, which is a vital research technique used to determine the age of organic artifacts in fields like archaeology, geology, and ecology.However, rocks and other objects in nature do not give off such obvious clues about how long they have been around.So, we rely on radiometric dating to calculate their ages.

The unstable isotope is brought to Earth by atmospheric activity, such as storms, and becomes fixed in the biosphere.When their emissions mix with the modern atmosphere, they flood it with non-radioactive carbon.This is not the first time in modern history that carbon-14 levels have changed.The study of fossils and the exploration of what they tell scientists about past climates and environments on Earth can be an interesting study for students of all ages.Teaching about Earth's history is a challenge for all teachers.
