Binnengewässer wie Flüsse, Seen oder Talsperren spielen im globalen Kohlenstoffkreislauf eine wichtige Rolle. In Hochrechnungen zum Kohlendioxidausstoß von Land- und Wasserflächen werden zeitweise trockenfallende Bereiche von Gewässern in der Regel nicht einbezogen. Die tatsächlichen Emissionen von Binnengewässern werden dadurch deutlich unterschätzt - das zeigen die aktuellen Ergebnisse eines internationalen Forschungsprojekts unter der Leitung von Wissenschaftler*innen des Helmholtz-Zentrums für Umweltforschung (UFZ) am Standort Magdeburg sowie des Katalanischen Instituts für Wasserforschung (ICRA). Die Studie ist im Fachmagazin Nature Communications erschienen.
