  2. Nitrogen (N2), oxygen (O2), and argon (Ar) make up for 99% of the atmosphere, but are not greenhouse gases. Water vapor (H2O), carbon dioxide (CO2), methane (CH4), ozone (O3), and nitrous oxide (N2O) are greenhouse gases. A greenhouse gas absorbs infrared radiation, whichcreates molecular vibrationand bending. Collisions transfer energy to heat the surrounding gas. But, what is a “greenhouse gas” anyway? Water vapor (H2O) vibration modes http://www.lsbu.ac.uk/water/vibrat.html
