Author cites Hannah Ritchie who insists on comparing billions of tons of raw fossil fuels vs. millions of tons of REFINED metals. Not vs. raw metal ores - that would be half the tonnage of fossils already. It is handwaved away in the discussion below the Ritchie's article as "armchair concerns" and "minor part" and "we don't know exactly". I think such serious topic deserves more intellectually honest analysis.
