英文摘要 | Reservoirs are essential for human populations, but their global carbon footprint is substantial (0.73-2.41 PgCO(2)-equivalent yr(-1)). Yet the temporal evolution of reservoir carbon emissions and their contribution to anthropogenic radiative forcing remains unresolved. Here we quantify the long-term historical and future evolution (1900-2060) of cumulative global reservoir area, carbon dioxide and methane emissions and the resulting radiative forcing. We show that global reservoir carbon emissions peaked in 1987 (4.4 TmolC yr(-1)) and have been declining since, due largely to decreasing carbon dioxide emissions as reservoirs age. However, reservoir-induced radiative forcing continues to rise due to ongoing increases in reservoir methane emissions, which accounted for 5.2% of global anthropogenic methane emissions in 2020. We estimate that, in the future, methane ebullition and degassing flux will make up >75% of the reservoir-induced radiative forcing, making these flux pathways key targets for improved understanding and mitigation. Reservoir-induced radiative forcing is increasing globally due to rising methane emissions outweighing declining carbon dioxide emissions, according to modelling based on reservoir surface area observations. |
