From what I can tell, methane has an atmospheric PPM of ~2 (compared to 400++ for CO2). The lower concentration, and the fact that methane generation is very diffuse presumably makes sequestration Hard.
- ComputerGuru 7y agoYes, when measured at surface levels, but I believe that, unlike CO2, methane is extremely concentrated within a region of the stratosphere (being significantly lighter than CO2 and O2); it’s not hard to imagine strategically placed sequestration “facilities” being able to get to it better. But I’m on my phone and it’s hard to find out what the max ppm at the elevations it is most concentrated at are. https://en.m.wikipedia.org/wiki/Atmospheric_methane#/media/File%3AAtmosphericMethane.png https://en.m.wikipedia.org/wiki/Atmospheric_methane#/media/F...
