The amount of carbon-14 in living plants and animals matches the amount in the atmosphere, but when plants and animals die, they no longer absorb carbon-14.
Nonradioactive carbon is now flooding the atmosphere, which creates a dilution effect.
But she hopes the projections in her study could also help scientists prepare for the changes to come.

For those who use carbon dating, like archaeologists, physicists, forensic scientists, and even art historians, the change in radiocarbon will complicate their work, according to Timothy Jull, a radiocarbon scientist.
“There are all these complicated effects,” said Jull, also a professor of geosciences at University of Arizona, who was not involved in the study.
