Kohlendioxid in der Atmosphäre trägt maßgeblich zur Klimaerwärmung bei. Klimaforscher vom Intergovernmental Panel on Climate Change (IPCC) schätzen, dass sich bei ungebremster Entwicklung die Kohlendioxid-Konzentration in der Atmosphäre bis zum Jahr 2100 verdoppeln wird. Das Gas verändert aber auch die Lebensbedingungen in den Ozeanen. Denn die Meere werden etwa ein Drittel des zusätzlichen Kohlendioxids aufnehmen. Dadurch wird der pH-Wert von 8,1 auf 7,8 fallen. Natürliche Kohlendioxid-Quellen in Papua Neuguinea geben Wissenschaftlern nun die einmalige Gelegenheit, die Veränderungen tropischer Korallenriffe zu untersuchen, wenn der vom Menschen verursachte Kohlendioxid-Ausstoß weiter ansteigt.
