# Rising CO2 emissions in oceans and Antarctica > Developing situation record from CLSTR: https://clstr.news/situations/rising-co2-emissions-in-oceans-and-antarctica > Updated: 2026-10-21T08:03:30.000Z. Sources: 6. Developments: 2. Research indicates significant shifts in global carbon cycles, specifically regarding CO2 fluctuations in oceanic and Antarctic environments. In the Indian Ocean, seasonal CO2 exchange in equatorial waters increased by 48% between 1980 and 2019, with seasonal variation in the southern Indian Ocean rising by 23%. In Antarctica’s Taylor Valley, studies published in Global Biogeochemical Cycles show a rapid increase in geogenic CO2 emissions. Average CO2 flux rose from 1.73 grams per square meter per day in 2020 to 9.49 grams in 2025, a 5.5-fold increase. Geochemical and isotopic analyses suggest this degassing originates from deep geological and hydrological systems passing through the permafrost rather than solely from surface biological processes. Geochemist Livio Ruggiero noted that these findings highlight critical connections between the atmosphere and deep subsurface geological systems. ## Timeline ### 2026-10-21: Antarctica Taylor Valley shows significant increase in geological CO2 emissions Scientific research in Antarctica's Taylor Valley shows a five-fold increase in CO2 degassing, suggesting deep geological carbon is escaping through the permafrost into the atmosphere. 2 sources. https://clstr.news/cluster/antarctica-taylor-valley-shows-significant-increase-in-geological-co2-emissions ### 2026-10-19: Global carbon cycles show rising CO2 fluctuations in oceans and Antarctica Research indicates rising CO2 fluctuations in the Indian Ocean and a five-fold increase in geogenic carbon emissions from Antarctic permafrost in Taylor Valley. 4 sources. https://clstr.news/cluster/global-carbon-cycles-show-rising-co2-fluctuations-in-oceans-and-antarctica --- Cite as: Rising CO2 emissions in oceans and Antarctica.
