De snel ontdooiende permafrost in het noordelijk halfrond kan onontdekte virussen, resistente bacteriën en zelfs radioactief afval uit de Koude Oorlog vrijgeven. Dat toont nieuw onderzoek van NASA en het Europees Ruimteagentschap (ESA) aan.
We at Sea Research Society's Environmental Affairs Department are very concerned of the melting permafrost terrain and methane clathrate deposits of the Arctic Ocean's sea bed (which are seeding Siberia's air once again with carbon-12). This is because Arctic Ocean's methane clathrates, methane (CH4) & carbon dioxide (CO₂) deposits are thought to be the world's largest reservoir of carbon.
Which effects did the heat wave of summer 2020 have in Siberia? geologists compared the spatial and temporal distribution of methane concentrations in the air of northern Siberia with geological maps. the methane concentrations in the air after last year’s heat wave indicate that increased gas emissions came from limestone formations.

La fonte de ces immenses terres gelées pourrait non seulement rejeter d’énormes quantités de carbone mais aussi du protoxyde d’azote, un gaz 300 fois plus réchauffant que le CO2, selon de nouvelles observations.
