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.
