carbon dioxide and methane.
Both CO2 and CH4 absorb outgoing infrared radiation and trap heat in the atmosphere. Helium is a light, non‑polar noble gas that does not absorb infrared and so is not a greenhouse gas. (Other important greenhouse gases include water vapor, nitrous oxide, ozone and various fluorinated gases.)
