2022年6月1日 · The most common greenhouse gases are (in order of atmospheric concentration) water vapor (H2O), carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and a suite of halogen-bearing gases (like fluorocarbons) that are derived from industrial activities.
What Are Greenhouse Gases and Why Do They Matter
2022年10月12日 · Greenhouse gases (GHGs) are a category of gases that absorb heat energy emitted from the planet's surface and they remain in Earth's atmosphere for a long time (from decades to centuries).
Greenhouse gas - Wikipedia
Greenhouse gases (GHGs) are the gases in the atmosphere that raise the surface temperature of planets such as the Earth. What distinguishes them from other gases is that they absorb the wavelengths of radiation that a planet emits, resulting in the greenhouse effect. [1]
