Ice cores don’t necessarily measure years, but changes in temperature. Have two weeks of cold weather followed by a warm week, and you might find a new layer, and that three weeks is now a ‘year’.
Someone found something like fifteen layers on a car in Knoxville in eight hours or so. Now, thats obviously an extreme case.
There is also the case of some German planes that got buried much deeper than theory says they should.
So I’d take what an ice core said with a pile of salt about the size of the ice core.
There is a parallel between evos and AGW people. Both are financed by government cheese, and both are heavily into fraud. Science based skeptics fight against gov’t funded propaganda.
