The Earth's atmosphere is 78 percent nitrogen, 21 percent oxygen and 1 percent other gases, including about 0.04 percent carbon dioxide.
We worry so very much over so very little. The Extra CO2 in the atmosphere is GOOD for the planet. Just look at greenhouse owners adding CO2 inside for better plant growth. Water vapor is much more of a threat, just try to do something about that.
