The major constituents of Earth's atmosphere, nitrogen (N 2) (78%), oxygen (O 2) (21%), and argon (Ar) (0.9%), are not greenhouse gases because molecules containing two atoms of the same element such as N 2 and O 2 have no net change in the distribution of their electrical charges when they vibrate, and monatomic gases such as Ar do not have vibrational modes. Hence they are al… Splet11. apr. 2024 · Greenhouse gases play a significant role in global warming.
