Is radiocarbon dating perfectly accurate video games about dating
Barnola et al wrote, "When the Vostok ice core data were compared with other ice core data (Delmas et al. 1982) for the past 30,000 - 40,000 years, good agreement was found between the records: all show low CO2 values [~200 parts per million by volume (ppmv)] during the Last Glacial Maximum and increased atmospheric CO2 concentrations associated with the glacial-Holocene transition." (Refer Historical Carbon Dioxide record from the Vostok ice core).
"We know from atmospheric measurements over the last 50 years that radiocarbon levels vary through the year, and we also know that plants typically grow at different times in different parts of the Northern Hemisphere.The most commonly used convention in radiocarbon dating is the unit bp (before present). Thus, when a radiocarbon lab reports an age of 10000 years bp, they are implying that the fossil would have died 10000 years before 1950 AD if the percentage of C present in the atmosphere 10000 years ago was the same as that in 1950 AD.However researchers know that this is not true, and have labored hard to calibrate the unit bp to true calendar years.This convention is necessary to avoid the confusion that would arise if different labs used different conventions.Various reasons could have altered the percentage of C that was present then.
