Accurate knowledge of <sup>13</sup>C isotopic signature (δ<sup>13</sup>C) of methane from each source is crucial for separating biogenic, fossil fuel and pyrogenic emissions in bottom-up and top-down methane budget. Livestock production is the largest anthropogenic source in the global methane budget, mostly from enteric fermentation of domestic ruminants. However, the global average, geographical distribution and temporal variations of the δ<sup>13</sup>C of enteric emissions are not well under ...[more]
