Evolving pattern of wetland and anthropogenic CH₄ C change over varying time horizon since 1765 using simple sustained pulse−response model. (A) Time series of SGWP for wetland and anthropogenic CH₄ emissions. (B) Comparison of RF dominance between wetland and anthropogenic emissions. Here RF dominance is defined as a ratio of SGWP from wetlands to SGWP from anthropogenic sources. Shaded areas represent the upper and lower range of wetland estimates. Here the SGWPs from wetland and anthropogenic emissions were calculated as integrated RF of CH₄ since preindustrial time (1765).
