Klimawandel: Wie speichern Böden CO2?

Kohlenstoffgehalt in Böden beeinflusst Klimamodelle

(PresseBox) (München, )
Der weltweite Ausstoß an Kohlendioxid (CO2) steigt weiter - allein 2012 gelangten 35,7 Milliarden Tonnen des Klimagases in die Atmosphäre*. Einen Teil des CO2 nehmen Ozeane, Pflanzen und die Böden auf. Sie bilden damit ein wichtiges Reservoir für Kohlenstoff, das die Freisetzung von CO2 eindämmt. Wissenschaftler haben jetzt festgestellt, wie organischer Kohlenstoff im Boden fixiert wird. Ihr Ergebnis: Der Kohlenstoff bindet nur an bestimmte Bodenstrukturen. Die Kapazität des Bodens CO2 aufzunehmen muss daher neu bewertet und in aktuelle Klimamodelle eingerechnet werden.

Aus früheren Studien ist bekannt, dass Kohlenstoff an sehr kleine mineralische Teilchen bindet.
