Nor can I, because I can't point you to the data because it is
unpublished. These Cornell people have published their interpretations
of the data they have discovered, but not the data itself. So their
results cannot be checked by their peers or anyone else. There is no way
to check whether their particular matches between different tree ring
sequences are the only possible ones, or just the possibility out of
several which fits best with their chronological presuppositions (see
the quotation below). This failure to publish one's data is bad science.
And yet everyone thinks they can depend on their results.

I don't rely on this argument. But the following from this same page
explains better the uncertainty I noted above:
