Did carbon monoxide throw off the carbon dating of the Shroud of Turin?

John Jackson, a physics lecturer at the University of Colorado at Colorado Springs has proposed that contamination by environmental carbon monoxide might have thrown off the carbon dating by as much as 1300 years.

 Christopher Ramsey, head of the Oxford University Radiocarbon Accelerator Unit agreed to test Jackson's hypothesis but, as of now, Jackson's hypothesis does not seem to work.

Much has been made, particularly by some journalists, of the following quotation by Christopher Ramsey. However, it is out of context. In full context, Ramsey seems to be referring to other reasons for continuing the testing despite, for now, being dubious of Jackson's hypothesis:

There is a lot of other evidence that suggests to many that the Shroud is older than the radiocarbon dates allow and so further research is certainly needed. It is important that we continue to test the accuracy of the original radiocarbon tests as we are already doing. It is equally important that experts assess and reinterpret some of the other evidence. Only by doing this will people be able to arrive at a coherent history of the Shroud which takes into account and explains all of the available scientific and historical information.
