    I’m not particularly sanguine about the accuracy of what was said in this video. The scientist for the advocacy NGO said most methane comes from natural gas wellheads, cows, and landfills. This is not true – the single largest source, by far, is wetlands.

    We also now know that the decomposition of surface vegetation produces methane directly, but this is not included in measurements. The EPA is supposedly looking into this. One would hope so, because the amount of deciduous biomass that rots is gigantic.

    I am also skeptical of the further statement that we have the means to cut methane emissions by half in the next decade, and that this would result in lowering the rate of AGW by 30%. (!) I have never heard such a statement before and it seems outlandish to me – total methane emissions are only 16% of anthropogenic USA CO2-equivalents and anthropogenic sources are smaller than natural sources.

      Swamp emissions aren’t anthropogenic, generally, (and I don’t think they’ve increased in the last 200years). The part that’s human-produced and human-controllable is what’s at issue, and the plane/satellite surveillance helps locate major industrial point sources that are the easiest to shut down.

      [What they’ll start seeing, of course, is greater CH4 emissions over time just from permafrost turning into swampland.]

      The point of the project is solid: You have to collect data on where the CH4 emissions are around the planet, and go after the lowest-hanging fruit first (some function of emission intensity and the ability to stop it). If it’s like most other science research, they’ll start to find surprises (for better or worse) once the data starts coming in.

      BTW, the CH4 table from the EPA “Inventory of US Greenhouse Gas Emissions” explicitly counts only LULUCF (Land Use, Land-Use Change and Forestry) emissions (i.e., outside of background emissions that predate the Industrial Revolution).
