WASHINGTON —The extreme rain events that have caused flooding across northern Australia may become an increasingly familiar occurrence, new research suggests. The study uses the growth patterns in near-shore corals to determine which summers brought more rain than others, creating a centuries-long rainfall record for northern Australia.
“This reconstruction provides a new insight into rainfall in northeast Queensland,” says Janice Lough, climate scientist of the Australian Institute of Marine Science (AIMS) in Townsville, Queensland, who authored the study. “These coral samples, which date from 1639 to 1981, suggest that the summer of 1973–1974 was the wettest in 300 years. This summer is now being compared with that record-setting one.” (more…)
