Wrong again! ICR isn't disputing the decay curve of C-14. You are deliberately changing the subject from the excess carbon in fossils claimed to be super old, to that of ICR's investigation of decay rates affecting other non-carbon dating methods. And even if ICR's investigation of non-carbon decay rates proves false, it doesn't eliminate the possibility of bad assumptions about ratios of parent/daughter elements.
The evidence is the excess carbon in the fossils. It is not floor noise, as the decay curve would not permit a floor that high and the equipment is senstive enough to accurately detect the amounts of carbon. It is possible that all the fossils were contaminated to the same extent, making sort of a floor contamination level instead of a floor noise. But nobody has yet quantified where that contamination would come from. They have practically ruled out radiation as being insufficient. And subteranean microbes produce C-13 instead of C-14.
And I noticed Diamond called you on the Tree Rings. I thought "science" demanded peer review. Here you have a couple of scholars claiming to have found tree ring records but they wont release the data to be examined by independent scientists!!! Yeah that's real credible. NOT!!!!
