What would the inverse of what we have now in the atmosphere be like?

Just curious what an inverted reality of ours would be like, where instead of having too much carbon dioxide in the atmosphere creating glasshouse gas effect, what would the inverse be like where we don’t have enough carbon dioxide in our atmosphere? What would the climate of earth be like?

Giant insects and way more fires! It's happened a few times in the history of our planet.

So you're saying the plot of Earth Defense Force 4.1 could be real if we remove enough CO2? That's hella incentive right there!

"Not enough CO2" probably would be bad news for trees and other photosynthesizing life, since it's what they breathe. But there was actually a period of time millions of years ago when the amount of oxygen in the atmosphere was much greater.

Yeah, if I'm remembering correctly, there was more oxygen in the atmosphere when dinosaurs were around. The more oxygen allowed animals to grow larger, uncluding bugs 😬

Yeah, bugs are most heavily size restricted by oxygen intake. It would be horrifying to let them have more.

Technically plants do respire oxygen and produce CO2, its just that the photosynthesis process produces more O2 than they need, so its a net offset 🤓

There have been experiments done since the 1800s proving that plants can survive in a closed environment, presumably by regulating the amount they photosynthesise, so there probably wouldn't be a global loss of plant life

Assuming we have a surplus of oxygen istead: Things would catch fire pretty quickly and pretty intensely.
