If we place two identical objects, one black and the other white, in the sun. The dark-colored object will absorb more heat than the light-colored object. The same thing happens with clouds or gases. Oxygen gases heat up at a much slower rate than carbon dioxide gases. Thus, the more carbon in the atmosphere, the more heat is retained.
Thus, the more we observe clouds of carbon traveling in the planet's atmosphere, the greater the heat trapped in the planet's atmosphere. There is a greater imbalance in the planet's ecosystems, and consequently an increase in environmental disasters, generating an increase in deaths on the planet.
Carbon dioxide absorbs the infrared spectrum and re-emits it in all directions, releasing half into space and the other half towards the earth, thus increasing the greenhouse effect. Thus, the more carbon, the more infrared reflecting off the earth.
On Mars, 95% of the atmosphere is made up of carbon dioxide, which is why anyone who observes the sky on Mars sees the sky red, due to infrared emission.
Thus, the more carbon dioxide, the more infrared is radiated onto the planet, generating extremely dangerous effects for the ecosystem.
