But that increased impact is a short term difference, right? The changes to air composition we cause by digging up in a few decades what had been sequestered off in millions of years are forever changes.

Good questions, I don’t know enough details. CO2 stays in the air for a long time, but not forever either. For sure though, it’s absorbed way too slowly than what we’re outputting now.
