    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.

        Then it would be saying 7.5tons tonnes which doesn’t make any sense.

        Looks like that’s the intention. The original paper uses Gt (gigatons): https://www.nature.com/articles/s41467-023-36990-3

      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).

What is geoscience?

Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth’s surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more…
