Eisbohrkerne sind für die Klimaforschung wichtig, da sie das einzige direkte Archiv sind, an dem Wissenschaftler die Zusammensetzung der Atmosphäre und hier insbesondere die Konzentration der Treibhausgase in der Vergangenheit messen können. Mit Hilfe neu entwickelter Isotopenverfahren ist es Wissenschaftlern des European Project for Ice Coring In Antarctica (EPICA) jetzt gelungen, die wichtigsten Prozesse zu identifizieren, die zu Änderungen der Methankonzentration während des Übergangs von der letzten Eiszeit in unsere Warmzeit führten. Die heute im Wissenschaftsmagazin nature erschienene Studie zeigt, dass Feuchtgebiete in Eiszeiten deutlich weniger Methan emittieren. Im Gegensatz dazu blieb der Ausstoß von Methan aus Waldbränden zwischen Eis- xgg Untuihul yghtkzjwnik tvpmqtko.
