Why Nitrogen is not a greenhouse gas? Oxygen and nitrogen are not greenhouse gases, because they are transparent to infrared light. These molecules are invisible because when you stretch one, it doesn’t change the electric field. In general, symmetrical molecules with only two atoms are not greenhouse gases. Why is sulfur dioxide not a greenhouse […]
