Re: data, method
So basically like most stuff on NPR the article in the OP is mostly bullshit.
So the dates for the 4.4 billion year ages for the zircons, once the younger contaminants and portions that lost Pb are removed, are still solid. What is not supported are the claims about the Earth environment 4.4 billion years ago. Is that correct?
