Fig. 1: Temporal trends and variations in wetland CH4 emissions during 2000–2021 relative to the baseline of 2000–2006 level in comparison to future projections12.

Shaded areas present 1σ range of the estimates from each future RCP. Annual total emissions from two estimates based on two climate forcing datasets, a ground-based dataset from the CRU at the University of East Anglia and a reanalysis-based MERRA2. Coloured lines represent ensemble mean of each future projection scenario.
