Gonna be honest - if the Great Dying didn't kill off all life on Earth, I don't see even especially reckless human activity doing it either. CO2 from that period went from 400 ppm to 2,500 ppm for reference, and Earth got like 8-10°C warmer then. Even shitty capitalist market mechanics would have abandoned carbon emissions at this point. If you want to turn Earth into Venus, you need to actively make it your goal. I mean burning every single last drop of fossil fuel faaaar after it's stopped being profitable.
