"Interestingly, in the upper halves of the Greenland ice cores, creationist and uniformitarian age assignments agree to within a factor of two or three of one another. Only in the bottom halves of the Greenland cores do uniformitarian and creationist age estimates dramatically diverge. Yet, the counting process is most difficult and uncertain in the bottom core sections, where ‘jumps’ in dust content are assumed to represent seasonal cycles. However, several factors together can plausibly account for overcounting in the bottoms of the Greenland cores.
First, seventyfold variations in dust content in the core bottoms
Second, individual storms (thousands of which would be expected in
a post-Flood Ice Age lasting hundreds of years) can change ice dust content.
Third, uniformitarian expectations of very thin annual layers in the bottom core sections contribute to overcounting.
Moreover, creationists have pointed out that the frequencies and thicknesses of tephra layers within the deep Antarctic ice cores are more consistent with young-Earth expectations as is the lack of erosion of the Gamburtsev Mountains beneath the East Antarctic ice sheet.
For the above reasons, I think creationists have refuted claims that ice cores demand an old Earth."
