Edit: okay after re-reading your comment I noticed I got it wrong and then typed the text, but I’ll leave it here just because it took me way too long to type it.
We have science, geology to be exact! There once was a reservoir beneath what‘s today‘s Russia of ~2x the amount of fossil fuel currently existing. That thing got ignited by magma, exploding an area the size of Russia and covering Eurasia in 2 ft of lava and making the CO2 levels extremely high, even rising the temperature to an average of 200 F (IIRC). This resulted in Mega Hurricanes the size of a continent with wind-speeds at the speed of sound, acid rain, etc etc, that lasted about 200 Million years, effectively killing 99.6% of all life on earth. Only after that long time then the Carbon-Silicate was balanced again.
The earth doesn’t care about that, it will recover. But we won’t.
