A head banger for some, not others...What would be the predominate GHG if there was no oxygen? Just for the fun of it. 27% 6 Votes

I%26#039;m going to guess you believe you can%26#039;t make methane without oxygen. Therefore, I%26#039;m going with ammonia since it has a lot of infrared bands in the right places, was found in relatively high concentrations in primordial anoxic atmospheres, and nobody has mentioned it yet.

Depends on what the hypothetical atmospheric chemistry IS, rather than just what it is not.

But the principal GHG in our atmosphere that contains no oxygen, is indeed methane. 14% 3 Votes
Methane maybe...

If oxygen didn%26#039;t exist, then there could be no carbon dioxide (CO2), carbon monoxide (CO), ozone (O3), or nitrogen dioxide (NO2)
If I remember back to my environmental chemistry days methane (CH4) is a greenhouse gas. 14% 3 Votes
