Fig. 6: Global CH4 emissions.
From: Sensitivity of Arctic CH4 emissions to landscape wetness diminished by atmospheric feedbacks
a, Difference in annual mean precipitation between the wet and dry trajectories for a climate stabilization under greenhouse gas concentrations corresponding to 2100 (SSP5-8.5). The diagonal lines cover areas of non-significant differences (P > 0.05) and oceans. b, The same as in a, but for annual mean CH4 emissions. c, CH4 budgets for permafrost regions north of 45° N, the latitudes between 45° N and 45° S, South America, Africa and Southeast Asia. Note that the emissions in non-permafrost regions were estimated using a different model version, the detailed description of which is given in ref. 59.
