Fossil Fuels Are Messing With Carbon Dating
Taco Cowboy writes: The carbon dating method used in determining the age of an artifact is based on the amount of radioactive carbon-14 isotopes it contains. The C-14 within an organism is continually decaying into stable carbon isotopes, but since the organism is absorbing more C-14 during its life, the ratio of C-14 to C-12 remains about the same as the ratio in the atmosphere. When the organism dies, the ratio of C-14 within its carcass begins to gradually decrease. The amount of C-14 drops by half every 5,730 years after death.
The fossil fuels we're burning are old — so old they don't contain any C-14. The more we burn these fossil fuels, the more non-C-14 carbon we pump into the atmosphere. If emissions continue as they have for the past few decades, then by year 2050 a shirt made in that year (2050) will have the same C-14 signature as a shirt worn by William the Conqueror a thousand years earlier.

As I am the one who submitted this article I need to point out an error
The radioactive C-14 isotopes do not decay into "stable carbon isotopes" but rather, into stable N-14 isotopes via beta decay !
Please accept my sincere apology for the error - it was the fault of no other but me alone, for not noticing that glaring error when I was copy-pasta-ing from articles of three different sites
Muchas Gracias, Señor Edward Snowden !
