Wie stark haben Vulkane in vergangenen Jahrtausenden die Atmosphäre mit Schwefel-Partikeln belastet? Um diese Frage zu beantworten, nutzen Wissenschaftler unter anderem Eisbohrkerne als Klimaarchiv. Doch ausgerechnet bei einigen zentralen vulkanischen Großereignissen der Vergangenheit unterscheiden sich die Ergebnisse, je nachdem, ob die Kerne aus der Antarktis oder aus Grönland stammen. Atmosphärenforscher des GEOMAR Helmholtz-Zentrum für Ozeanforschung Kiel und des MPI für Meteorologie Hamburg haben jetzt eine Erklärung gefunden, die die Interpretation der Eisbohrkerne deutlich verbessern könnte. Ihre Studie ist in der aktuellen Ausgabe der internationalen Fachzeitschrift "Journal of Geophysical Research - Atmosphere" erschienen.
