Computer modeling is only as useful as the viability of the model as well as the relevancy and accuracy of the data input.Actually the article is about a gaggle of so-called "scientists" making a huge leap of faith in proclaiming that the Romans' use of lead in everything from aqueducts to cookware and drink wear exhibits global implications which can be measured and quantified via analysis of arctic ice cores. Give me a break! I have a degree in agronomic science and 30+ years experience in its application. I have a thorough understanding of the electro-chemical interactions between naturally occurring molecules and elements. To say that their claim regarding Roman lead in arctic ice is utterly preposterous and lacking in scientific merit is an understatement. They fail to even consider volcanic activity as the source of lead in arctic ice. Ever hear of Mt Vesuvius? They make Fauci et al look legitimate in comparison.
That's a fancy way of saying:
Garbage in-Garbage out
Build the model right and it'll spit out whatever results you want it to.
