Bisher gingen Wissenschaftler davon aus, dass Viehhaltung auf großflächigen Weiden zur stetig wachsenden Lachgaskonzentration in der Atmosphäre und damit zur globalen Erderwärmung beiträgt. Doch im Gegenteil: Dass Viehhaltung in Steppen- und Präriegebieten die Emission des Treibhausgases reduziert, konnte ein fünfköpfiges Forscherteam um Klaus Butterbach-Bahl vom Karlsruher Institut für Technologie (KIT) zeigen. Für ihre Langzeitstudie erhalten die Ökosystem-Klimaforscher jetzt den mit 50.000 Euro dotierten Wissenschaftspreis des Stifterverbandes - Erwin Schrödinger-Preis 2013, den der Stifterverband für die Deutsche Wissenschaft und die Helmholtz-Gemeinschaft jedes Jahr gemeinsam vergeben.
Nach Kohlenstoffdioxid und Methan gehört Lachgas zu den wichtigsten Gasen, die zum Treibhauseffekt und Klimawandel beitragen.
