THE EVOLUTION OF THE EL NINO-SOUTHERN OSCILLATION IN SOUTHEAST AUSTRALIA
Grant number: IN140100050 | Funding period: 2014 - 2016
El Niño events starve southeast Australia of rainfall, resulting in droughts and wildfires. El Niño activity is projected to amplify as global temperatures rise, heralding a serious threat to Australia's water security and the incidence and magnitude of wildfires. The key to understanding the potential effects of future changes in El Niño activity lies in the past. El Niño activity has varied substantially over the last 12,000 years. This project will reconstruct the response of southeast Australian climate, vegetation and fire activity to changes in El Niño activity over this period using lake sediments located in El Niño sensitive locations in Tasmania.
