      ...according to the story, is 25 or 72 times less greenhousy. So if it's that multiplier that underlies the alarm presented, then the absence of that multiplier should work the other way.

      Current methane levels are around 1 or 2 parts per billion by volume. To even add, say, 1% to overall CO2 levels, it would have to increase by a factor of over 15,000-30,000, assuming I carried Avogadro's number or whatever correctly.

      •  OK, but it is both rather than either/or. (0+ / 0-)

        I do think I misread the intent of your comment. A methane molecule breaks down in the presence of oxygen to form CO2 and water. So 2 greenhouse gasses are both involved— a stronger one that lasts a few decades before breaking down to a form that has a lesser impact, but persists for much longer. So the effects are additive, I think. That was my point.
