Detailed explanation-1: -CO2 makes up only about 0.04% of the atmosphere, and water vapor can vary from 0 to 4%. But while water vapor is the dominant greenhouse gas in our atmosphere, it has “windows” that allow some of the infrared energy to escape without being absorbed.

Detailed explanation-2: -What’s in the Air? By volume, the dry air in Earth’s atmosphere is about 78.08 percent nitrogen, 20.95 percent oxygen, and 0.93 percent argon. A brew of trace gases accounts for the other approximately 0.04 percent, including the greenhouse gases carbon dioxide, methane, nitrous oxide and ozone.

Detailed explanation-3: -Carbon dioxide (CO2 ) constitutes about 0.03% (300 parts per million) of the atmospheric gases. Whereas, nitrogen comprises 70% and oxygen 21% of the atmospheric gases.

Detailed explanation-4: -Carbon occupies about 0.03% of the earth’s atmosphere.

Detailed explanation-5: -The proportion of carbon dioxide in the atmosphere is about 0.03% Q. About a hundred years ago, the proportion of carbon dioxide in air was about 0.029%. Today it is 0.035%.
