Water is the most powerful greenhouse gas because it’s so abundant. Because it is so abundant though, the absorption lines are pretty much maxed. Besides the available quantum states (1 and 2 atom molecules cannot be GHGs) which make CFCs more powerful, the main impact on GHG strength is relative abundance. Methane is rare, so every atom is important, CO2 is uncommon, and H2O is common. I guess that makes CFCs a foil, lol. |
