Fig. 3: Simulated trends in Arctic CH4 emissions and wetland area.
From: Sensitivity of Arctic CH4 emissions to landscape wetness diminished by atmospheric feedbacks
a, Difference in the soil CH4 emissions between the wet and dry scenarios averaged over the period 2080–2100. b, Simulated soil CH4 emissions averaged over the Arctic permafrost regions (Fig. 2c) for the wet and dry scenarios. The blue lines show the mean of the ensemble of wet JSBACH simulations, with the thick line indicating the 10 year running mean. The shaded area shows the spread between the ensemble minimum and maximum. The dry ensemble is shown in yellow. c, The same as in b, but for the simulated extent of waterlogged soils during the season May to October (MJJASO); that is, those areas where soil organic matter decomposes under anoxic conditions. d, The same as in a, but for the relative difference in the extent of waterlogged soils (ΔRelFracwet).
