Not that it matters much for my understanding, as these numbers are too big for my brain to grasp anyway, but what does that unit prefix "tn" stand for?
While reading the article in my head I read it as "tera tonne" but wouldn't that be "Tt"?
I hope it's at least a metric tonne and not one of the other weird short or long tonnes.
I guess it means
freedomamerican tons.Judging by similar articles, it's "7.5 trillion tonnes." I assume metric tonne because of the spelling (usually I've only seen short or long ton spelled ton, although it may vary by region).
