Even the staunchest advocates of carbon dating admit that it gives errors for material that is younger than 150 years or older than 50,000 years. The errors for material younger than 150 years is ascribed to changes in the ratio of C-14 to C-12 in the atmosphere.<ref>http://www.talkorigins.org/indexcc/CD/CD011.html</ref> The errors for material older than 50,000 years is ascribed to statistical uncertainties inherent in the loss of multiple half-lives. | Even the staunchest advocates of carbon dating admit that it gives errors for material that is younger than 150 years or older than 50,000 years.
