Methan löste Artensterben aus

Februar 14, 2004 by admin 

Methan löste nach Ansicht von Forschern der Northwestern-Universität vor 250 Millionen Jahren das massive Artensterben aus. Die Gas-Explosion habe die Schichten des Ozeans durcheinander gewirbelt und die Atmosphäre mit Kohlendioxid angereichert. Nach der Theorie bildeten sich im Meer große Vorräte an Methan aus pflanzlichen Verfallsprozessen und gefrorenen Methanhydraten, die durch einen kleineren Meteoriteneinschlag an die Oberfläche kamen und explodierten. Die Sprengkraft soll das zehntausendfache der weltweit verfügbaren nuklearen Waffen übertroffen haben.
