Here we use an ensemble of atmospheric inversions informed by<br \/>\nsurface or satellite methane observations to infer emission changes during<br \/>\nthese two years relative to 2019. Results show global methane emissions<br \/>\nincreased by 20.3\u00b19.9 and 24.8\u00b13.1 teragrams per year in 2020 and 2021,<br \/>\ndominated by heightened emissions from tropical and boreal inundated areas,<br \/>\naligning with rising groundwater storage and regional warming. Current<br \/>\nprocess-based wetland models fail to capture the tropical emission surges<br \/>\nrevealed by atmospheric inversions, likely due to inaccurate representation of<br \/>\nwetland extents and associated methane emissions. Our findings underscore<br \/>\nthe critical role of tropical inundated areas in the recent methane emission<br \/>\nsurges and highlight the need to integrate multiple data streams and modeling<br \/>\ntools for better constraining tropical wetland emissions.<\/p>\n","protected":false},"template":"","meta":{"_acf_changed":false,"_searchwp_excluded":"","_id":"","_status":"PUBLISHED","_sync_date":"2026-09-11 15:00:00","footnotes":""},"nva_tax_category":[1099],"class_list":["post-119301","nva_publication","type-nva_publication","status-publish","hentry","nva_tax_category-scientific-journal-publication"],"acf":[],"_links":{"self":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/119301","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication"}],"about":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/types\/nva_publication"}],"version-history":[{"count":0,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_publication\/119301\/revisions"}],"wp:attachment":[{"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/media?parent=119301"}],"wp:term":[{"taxonomy":"nva_tax_category","embeddable":true,"href":"https:\/\/nilu.gnist.dev\/en\/wp-json\/wp\/v2\/nva_tax_category?post=119301"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
