A new global analysis reveals that if we allow seagrass decline to continue unchecked, as much as 1,154 Tg of Carbon Dioxide could be released back into the atmosphere from meadows at risk, accelerating the climate crisis we are trying to prevent.

Havets kustzoner pekas ut som viktiga naturliga kolsänkor globalt, särskilt områden med växtlighet som sjögräsängar och mangrove. I bräckta kustmiljöer vet vi desto mindre om kolinlagring, men en ny studie visar nu att även grunda, avsnörda Östersjövikar är betydande sänkor för både kol och näring.
