Possible errors in carbon dating
But by 2003 new data came in and it was clear that . Temperatures appear to control carbon, and while it’s possible that carbon also influences temperature these ice cores don’t show much evidence of that.After temperatures rise, on average it takes 800 years .
The fact that temperature leads is not controversial. It’s impossible to see a lag of centuries on a graph that covers half a million years so I have regraphed the data from the original sources, here and here, and scaled the graphs out so that the lag is visible to the naked eye.
In the 1990′s the classic Vostok ice core graph showed temperature and carbon in lock step moving at the same time.
It made sense to worry that carbon dioxide did influence temperature.
Its use could have for example helped to determine the moment when the papers in the Bárcenas [corruption claims] case were written." To conduct the research work, the Department of Analytical Chemistry had the collaboration of the company Investigaciones Forenses Documentales LEYAS and Magdalena Ezcurra holder of a Ph D from the UPV/EHU.
This company also supplied the knowledge about the current problems in dating documents, real cases that had been subjected to legal examination.
