Reimer and colleagues point out that Int Cal13 is just the latest in calibration sets, and further refinements are to be expected.
For example, in Int Cal09's calibration, they discovered evidence that during the Younger Dryas (12,550-12,900 cal BP), there was a shutdown or at least a steep reduction of the North Atlantic Deep Water formation, which was surely a reflection of climate change; they had to throw out data for that period from the North Atlantic and use a different dataset.

Archaeologists, on the other hand, provide proof of authenticity of a certain artifact or debunk historical or anthropological findings.
Archaeology has undoubtedly enriched mankind’s history like no other science.
It was the first absolute scientific method ever invented: that is to say, the technique was the first to allow a researcher to determine how long ago an organic object died, whether it is in context or not.
Shy of a date stamp on an object, it is still the best and most accurate of dating techniques devised.
Given relatively pristine circumstances, a radiocarbon lab can measure the amount of radiocarbon accurately in a dead organism for as long as 50,000 years ago; after that, there's not enough C14 left to measure. Carbon in the atmosphere fluctuates with the strength of earth's magnetic field and solar activity.
You have to know what the atmospheric carbon level (the radiocarbon 'reservoir') was like at the time of an organism's death, in order to be able to calculate how much time has passed since the organism died.
We should see some interesting results in the very near future.
History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past.
The latest curves were ratified at the 21st International Radiocarbon Conference in July of 2012.Tags: Adult Dating, affair dating, sex dating
