In 1860 atmospheric co2 was at 288 ppm [0]. By 1960 it was around 317 ppm [1]. A difference of 29 ppm which works out to about 226.78 gigatons of co2 [2].

In 2022 we emitted 37.5 gigatons of co2, up 0.9% from 2021 [3]. We are currently emitting an "industrial revolution" of co2 every ~6 years.

Consulting Wikipedia, I guess I'm talking about "Industrial Revolutions Units" then.

Is this a real thing? I can't find anything about it on wikipedia.
