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?

Whole universe filled with air, while earth is surrounded by vacuum.

That Time Oxygen Almost Killed Everything

KestrelAlex ,

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!

FleetingTit ,

He’s assuming that the inverse of too much CO2 is too much O2.

KestrelAlex ,

You got me there, my brain did just jump to high O2

nodsocket ,

That would be the case for extra O2, not for less CO2.

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

Probably an ice age

“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 😬

Deestan ,

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

Ferb, I know what we’re gonna do today.

Rudee ,

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

BlameThePeacock ,

Frozen, but…

Who cares? Everything important would be dead. Photosynthesizing plants require CO2 to live.
