Global termite methane emissions have been affected by climate and land-use changes.

ABSTRACT: Termites with symbiotic methanogens are a known source of atmospheric methane (CH₄), but large uncertainties remain regarding the flux magnitude. This study estimated global termite CH₄ emissions using a framework similar to previous studies but with contemporary datasets and a biogeochemical model. The global termite emission in 2020 was estimated as 14.8 ± 6.7 Tg CH₄ year^-1, mainly from tropical and subtropical ecosystems, indicating a major natural source from upland regions. Uncertainties associated with estimation methods were assessed. The emission during the historical period 1901-2021 was estimated to have increased gradually (+ 0.7 Tg CH₄ year^-1) as a result of combined influences of elevated CO₂ (via veg
