From what I can see, yes, methane is abstractly a worse greenhouse gas. However its absorption band is within that of water vapor. Since water vapor is plentiful around the blue marble, methane doesn’t really cause any problems.
- mturmon 7y agoThis is incorrect, it’s well established that methane is a more potent GHG. See the reply here: https://news.ycombinator.com/item?id=21485738 https://news.ycombinator.com/item?id=21485738
- virmundi 7y agoWhat’s not taken into conservation with that comment is that methane at those altitudes does not impact much because the energy is radiate back to space.
- mturmon 7y agoYou have doubled down on a casual assertion ("methane is not a significant greenhouse gas") because you don't understand radiative transfer in the upper atmosphere. It's OK, radiative transfer is complex. Your options are to accept this consensus, or do a lot more study than you have.
