I never said such a thing. I said the article presented no data. What is the source of data from which the graph was constructed? Well, Oard provides his reference (5), which is:
http://onlinelibrary.wiley.com/doi/10.1029/95JD01174/full. Here's the first sentence of his description providing the reference to the graph:
"Figure 1. The oxygen isotope ratio down the GRIP ice core, central Greenland (from Wolff et al.).5"
The Wolff et al paper he cited stating oxygen isotope ratio being the data type is erronous. The data used in the Wolff et al paper is from electrical conductivity (EMC) and Dielectric profile (DEP) which is based on acidity, not on oxygen isotopes. Additionally, Oards mention of a 110 kyr ice core record is a misdirection, especially in conjunction with his further mention of oxygen isotopes. Oxygen isotope chronology is only good up to generally 12 kyr with a maximum use up to 20 kyr. As a side note, Carl Wieland, in his article about the "Lost Squadron", also misrepresents the oxygen isotope chronology limits.
