Talsperren dienen unter anderem als Reservoire für Trinkwasser, die landwirtschaftliche Bewässerung oder den Betrieb von Wasserkraftanlagen. Bisher ging man davon aus, dass Talsperren ungefähr so viel Kohlenstoff speichern, wie sie in Form von Treibhausgasen an die Atmosphäre abgeben. Forscher des Helmholtz-Zentrums für Umweltforschung (UFZ) am Standort Magdeburg konnten in Kooperation mit spanischen Wissenschaftlern des Katalanischen Instituts für Wasserforschung (ICRA) in Girona sowie der Universität Barcelona nun aber zeigen, dass Talsperren zweimal mehr Kohlenstoff freisetzen als sie speichern. Die Studie ist im Fachjournal Nature Geoscience erschienen.
