There was already a period in the history of the Earth when the CO2 content was almost 20 times higher than the present one. It was a Cambrian. And in Devon, the CO2 content was 12 times higher. As we know, the planet didn't boil then, and life didn't die. Exactly the opposite, it was a time when it bloomed.
The biosphere was tremendous. The biomass on Earth was many times larger. It was in the Devonian period that trees began to grow on land. Unfortunately, there were no tree-destroying xylotrophs in Devon yet, whose enzymes can break down lignin. In other words, trees have not rotted yet. Instead, they turned into coal and oil by removing CO2 from the atmosphere. Now we bring back the CO2 that was taken from the atmosphere at the beginning of the biosphere back into the atmosphere, and this has a positive effect on climate.
