Unravelling Western Australia's Stormy Past - A Precisely-Dated Sediment Record of Cyclones over the past 7000 years. Australia has a vast coastline, much of which is vulnerable to cyclone impact. Clearly, historical human experience does not comprehend what the climate system is capable of in terms of epic storms. Our effort to understand the storm risks of the past is complicated by the limited length of the instrumental record which reaches back only 150 years of European settlement in tropic ....Unravelling Western Australia's Stormy Past - A Precisely-Dated Sediment Record of Cyclones over the past 7000 years. Australia has a vast coastline, much of which is vulnerable to cyclone impact. Clearly, historical human experience does not comprehend what the climate system is capable of in terms of epic storms. Our effort to understand the storm risks of the past is complicated by the limited length of the instrumental record which reaches back only 150 years of European settlement in tropical areas of Australia. This project will reconstruct the history of storms and cyclones using sedimentary signatures in Western Australia over the past 7000 years to assess storm and cyclone risks under changing future climates in a regional context.Read moreRead less
Exposure dating with manganese-53, neon-21 and beryllium-10: a new toolkit for studying long-term landscape evolution. Australia today is the driest inhabited continent but this was not always the case. Tens of millions of years ago the climate of Australia was considerably wetter. Then, several million years ago, aridity in Australia developed producing most of the desert features of the red Centre that we see today. The age of our deserts and other arid features are not, however, well known.

Australia today is the driest inhabited continent but this was not always the case. Tens of millions of years ago the climate of Australia was considerably wetter. Then, several million years ago, aridity in Australia developed producing most of the desert features of the red Centre that we see today. The age of our deserts and other arid features are not, however, well known. This project will determine the age of desertification in Australia, thereby enhancing our understanding of such processes and the response of our landscape to changing climate.

Environmental impacts of climate change in the Nile basin over the past 30,000 years. There is growing international and national concern over the possible environmental, economic and social impacts of global and regional climate change. This project brings together a multi-disciplinary team of internationally recognised research leaders and the resources they command to investigate the environmental impacts of climatic changes in the Nile basin over geologically recent times. The outcome will b ....Environmental impacts of climate change in the Nile basin over the past 30,000 years. There is growing international and national concern over the possible environmental, economic and social impacts of global and regional climate change. This project brings together a multi-disciplinary team of internationally recognised research leaders and the resources they command to investigate the environmental impacts of climatic changes in the Nile basin over geologically recent times. The outcome will be a more comprehensive understanding of how a major river system responds to global and regional climate change, and will provide an enhanced conceptual basis for anticipating how drainage systems such as the Murray-Darling could respond to future change.Read moreRead less
