Abstract The positive response of wetland methane (CH 4 ) emissions to climate change is an important yet uncertain Earth-system feedback that amplifies atmospheric CH 4 concentrations. Here, using a wetland model, we report intensified wetland CH 4 emissions during 2000–2021, corresponding with 2020 and 2021 being exceptional years of growth. Our results highlight the need for sustained monitoring and observations of global wetland CH 4 fluxes to document emerging trends, variability and underlying drivers.
