Guy. Love your work. Really. But this topic is SO much more nuanced. Humans and their current habitat couldn’t survive in the same conditions in which the earth has spent 99 percent of it post-Cambrian explosion epochs. It’s called “hot bulb”. And it’s great for reptiles. Devastating for mammals. Yes. The CO2 “emergency” is a politicised power play, hoax. But no, we can’t jump to multiples of higher levels of higher CO2 (or oxygen! For that matter) and survive. We have to move at evolutions scale to meet the organic changes. 🧬 I only answered because I love your work and you seem genuinely confused.
