The initials BP or bp and rarely B. While BP is also used generally as an imprecise estimate of an age of an object or event, the use of it in science was made necessary by the quirks of the radiocarbon methodology. Radiocarbon dating was invented in the late 's, and within a few decades, it was discovered that while the dates retrieved from the method have a sound, repeatable progression, they are not a one-to-one match with calendar years. Most importantly, researchers discovered that radiocarbon dates are affected by the amount of carbon in the atmosphere, which has fluctuated greatly in the past for both natural and human-caused reasons such as the invention of iron smelting , the Industrial Revolution , and the invention of the combustion engine. Tree rings , which keep a record of the amount of carbon in the atmosphere when they are created, are used to calibrate or fine-tune radiocarbon dates to their calendar dates. Scholars use the science of dendrochronology, which matches those annular rings to known carbon fluctuations. That methodology has been refined and improved several times over the last few years.
