Wenn der Kohlendioxidgehalt der Atmosphäre steigt, heizt sich die Erde nicht nur auf, auch Wetterextreme wie anhaltende Dürren, Hitzewellen, Starkregen oder extreme Stürme dürften sich häufen. Ob die extremen Klimaereignisse dazu führen, dass Landökosysteme zusätzliches Kohlendioxid freisetzen und somit den Klimawandel verstärken, ist eine der großen offenen Fragen in der Klimaforschung. Ihr ist nun ein internationales Forscherteam um Markus Reichstein, Direktor am Max-Planck-Institut für Biogeochemie in Jena, nachgegangen. Die Wissenschaftler fanden dabei heraus, dass die Landökosysteme wegen der extremen klimatischen Ereignisse jährlich per Fotosynthese etwa elf Milliarden Tonnen weniger Kohlendioxid aufnehmen, als sie es ohne Extremereignisse könnten. Das entspricht etwa quvga Smeanlp fls ezhbdbojrk Yiaxpqsfanqq-Mqwpvhcuoh heq Nuwt.
