Do you think we'll see an emergence of CO2 eaters?
If the UN could pass a unilateral mandate that dictated all nations production facilities to use CO2 capture at all types of plants. That could have helped make things significantly better.
There are ways to capture CO2 out of the year and dose plants and other fauna to supergrow them. It's a crude simplification, but the idea is that you can expose much plant life (and animal life) with CO2 to make them grow. Massive levels of CO2 in the atmosphere during the periods of the Dinosaurs allowed animals and trees to grow to absurd sizes.
But the temperature would be unbearable for humans. It would be impossible to breath. It's possible that we'd die if we returned to that.
There was so much CO2 in the atmosphere in the Jurassic Era, that the largest dinosaurs, like the Brontosaurus variants like the Argentinasaurus became so big, that if they got any bigger, the pressure from their weight would exceed what their bone mass would be able to handle due to the force of gravity.
These beasts lived in a climate so abundance with greens that they'd eat 18-20 hours a day- Similar to modern Elephants. Only Elephants are 10x smaller.
One of the main ideas about teraforming mars is about harvesting the greenhouse effect by releasing lots of CO2 from melting the poles. People theorize that if you put heat shields that targeted the poles, the evaporation would cause CO2 to create a stable atmosphere for the surface of Mars. It would be thin, but over a 20-30 year timespan of sun reflection, it could become breathable similar to earth. Or that's the theory at least.
Figuring out what we can do with the C02 is going to be interesting. Can C02 captured from the air be combined with something to make solids? Imagine if it could be a build material we would put in our metals, ore and other materials? If we could recycle it in a different form.
