How green were our deserts? Evidence for Late Quaternary climate change and the source of water in the Lake Eyre basin

This project addresses the National Research Priority of Environmentally Sustainable Australia by examining evidence for what has controlled climate change and variable runoff in the vast Lake Eyre basin. It will provide evidence for why Australia, presently the world's driest inhabited continent, has as recently as medieval times supported large lakes holding many cubic kilometres of fresh water adjacent to the now-barren Flinders Ranges. It will show if this water had a tropical or temperate source, fundamental information for understanding Australia's past climate, and allow predictions of future climate to be based on firm evidence.
