is a term for radiocarbon dating based on timestamps left by above-ground nuclear explosions, and it is especially useful for putting an absolute age on organisms that lived through those events.

In The Cosmic Story of Carbon-14 Ethan Siegel writes: The only major fluctuation [in carbon-14] we know of occurred when we began detonating nuclear weapons in the open air, back in the mid-20th century.

CCS technology mitigates the release of carbon dioxide (CO2) from the combustion of fossil fuels.

Three potential approaches allow power plants to capture CO2: Petra Nova’s post-combustion CO2 capture system began operations in January 2017.

It can be used on objects as old as about 62,000 years. Atoms of the same element that have different numbers of neutrons are called isotopes. Most carbon on Earth exists as the very stable isotope carbon-12, with a very small amount as carbon-13.The post-combustion process is energy intensive and requires a dedicated natural gas unit to accommodate the energy requirements of the carbon-capture process.The carbon dioxide captured by Petra Nova’s system is then used in enhanced oil recovery at nearby oil fields. Rather, it's a way to determine the age of organic remains such as bone, teeth, and seeds by finding out how much carbon-14 is left in the remains. At the very least you'll find out what it's like to date a 9,000-year-old skeleton such as Kennewick Man's.

Inscriptions, distinctive markings, and historical documents can all offer clues to an artifact's age.The Petra Nova facility, a coal-fired power plant located near Houston, Texas, is one of only two operating power plants with carbon capture and storage (CCS) in the world, and it is the only such facility in the United States.
