Fig. 4: Pattern correlation analysis of wetland methane emissions with main drivers.
From: Drivers of persistent changes in the global methane cycle under aggressive mitigation action
Pattern correlations of global annual mean data is presented for: a the contemporary period (2000s), b the mid-twenty first century (2050s), and c the end of the 21st century (2090s). The correlation is calculated for the differences between the respective decade and the 1850s for each of the drivers and wetland methane emissions. The same data as shown in Fig. 3 is used and is thus limited to land points only; years denote the midpoints for each decade. In the plots ΔTsfc denotes change in surface temperatures, ΔPCPN refers to changes in precipitation, ΔNPP indicates changes in NPP, Δwtlfrac denotes changes in the global wetland fraction, and Δwtlems identifies changes in wetland methane emissions.
