ABSTRACT

Chappellaz et al. 1993

Chappellaz, J.A., I.Y. Fung, and A.M. Thompson, 1993: The atmospheric CH4 increase since the Last Glacial Minimum: (1). Source estimates. Tellus, 45B, 228-241, doi:10.1034/j.1600-0889.1993.t01-2-00002.x.

An estimate of the distribution of wetland area and associated CH4 emission is presented for the Last Glacial Minimum (LGM, 18 kyr BP, kiloyear Before Present) and the Pre-Industrial Holocene (PIH, 9000-200 years BP). The wetland source, combined with estimates of the other biogenic sources and sink, yields total source strengths of 120 and 180 Tg CH4 / yr for LGM and PIH respectively. These source strengths are shown to be consistent with source estimates inferred from a photochemical model, and point to changes in wetland CH4 source as a major factor driving the atmospheric CH4 increase from LGM to PIH.
