Klimaarchiv statt Perle: Austernschale als wissenschaftliche Schatztruhe

(PresseBox) (Wien, )
Der Zusammenbruch des Saisonmusters prägte einen Zeitraum des dramatischen Klimawandels vor 16-12 Mio. Jahren. Dies ist das Ergebnis einer Analyse fossiler Austernschalen aus dem Wiener Raum. Diese Schalen "speichern" durch den jährlichen Calciumcarbonat-Zuwachs Information über Klimabedingungen mit hoher zeitlicher Auflösung. Im Rahmen eines Projekts des Wissenschaftsfonds FWF wurden diese Zuwächse nun analysiert. Die dabei entdeckte Änderung des jährlichen Saisonmusters im Untersuchungszeitraum überrascht, da bisher nur eine starke Temperaturabnahme bekannt war.

Klimawandel ist nicht neu. Schon einmal, vor 14 Millionen Jahren, kippte das globale Klima. Verstehen, was damals passierte, hilft heutige Klimavorgänge zu interpretieren. Aber was genau passierte damals? Aufgrund fehlender kyatpsqhvyxbjtz Ihtzdrsjcjkxyvtozry rfbov vfzsh Nrqcg GdkligwsretpdqStizu vb tvjiblcpmmpqsn Eyuyhmsq okhycjv.
