See also a more recent post here for an even less technical discussion.) concentrations have risen from 280 to nearly 380 parts per million (ppm).

2) Since carbon was not measured in the atmosphere during the Industrial Revolution as it has been since, and that it was not constant any more than measured changes of nuclear testing, which peaked in 1965, meaning it was less before and after, how do we know how much compensation in the measurement that needs to be given from Industrial Revolution carbon change?

With nuclear testing, we know that the 1990 atmosphere carbon was only 20% higher than the theoretical 1950 level (dropping some 80% over that time), yet the Industrial Revolution lasted not only some 100 years, we do not know how much additional atmospheric carbon existed at any point during that time, and at what point it reached its peak, or to what degree it decomposed over time.

Ninety-five percent of the activity of Oxalic Acid from the year 1950 is equal to the measured activity of the absolute radiocarbon standard which is 1890 wood.

This is the International Radiocarbon Dating Standard.

Note: This is an update to an earlier post, which many found to be too technical.

The original, and a series of comments on it, can be found here.

This is calculated through careful measurement of the residual activity (per gram C) remaining in a sample whose age is Unknown, compared with the activity present in Modern and Background samples. Thus 1950, is year 0 BP by convention in radiocarbon dating and is deemed to be the 'present'.

You can get an idea of the relationship between C14 and age at the Carbon Dating calculator page. 1950 was chosen for no particular reason other than to honour the publication of the first radiocarbon dates calculated in December 1949 (Taylor, 19).

In fact, many important archaeological artifacts have been dated using this method including some of the Dead Sea Scrolls and the Shroud of Turin.

Though radiocarbon dating is startlingly accurate for the most part, it has a few sizable flaws.

The technology uses a series of mathematical calculations—the most recognizable of which is known as half-life—to estimate the age the organism stopped ingesting the isotope.
