Short summary

Methane is a powerful driver of climate change, yet emissions from wetlands and farming remain uncertain. We improved a global vegetation model that links water, plants and soils to methane production and release. The model now captures waterlogged areas, methane creation and escape, and flood-tolerant plants. It reproduces global wetland patterns and emissions more realistically, helping assess how climate and land-use change may affect future methane release and improve climate projections.
