      =v= Hard to do without seeing how they arrived at their figures.
      Much would seem to hinge on the assertion that methane has "21
      times the warming potential of CO2" and what "warming potential"
      actually means.

      =v= Their writing is a bit sloppy:

      | All told, livestock are responsible for 18% of greenhouse-gas
      | emissions worldwide, according to the U.N. -- more than all
      | the planes, trains and automobiles on the planet.

      No, the transport sector is responsible for more emissions than
      that, any way you slice it. The question would actually seem
      to be which type of emission has more impact.
