East Asian Monsoon response to periods of abrupt global change. This proposal aims to investigate the response of the East Asian Monsoon to abrupt climatic change, under baseline states of both warm and cool climate. The research is significant as it utilises unique, precisely dated sediments from Japan, and novel approaches to quantifying spatial and temporal climate patterns. The research will improve understanding of the nature and causes of decadal-scale changes in monsoon precipitation, wit ....East Asian Monsoon response to periods of abrupt global change. This proposal aims to investigate the response of the East Asian Monsoon to abrupt climatic change, under baseline states of both warm and cool climate. The research is significant as it utilises unique, precisely dated sediments from Japan, and novel approaches to quantifying spatial and temporal climate patterns. The research will improve understanding of the nature and causes of decadal-scale changes in monsoon precipitation, with relevance for constraining the trajectory of the future monsoon, and the risks of prolonged drought and flood. The findings will benefit the Asian people, for whom the monsoon has major economic, social and environmental importance. In turn, this will benefit Australia, via economic and climatic ties to Asia.Read moreRead less
Is there a climatic tipping point for Antarctic Bottom Water formation? Antarctic Bottom Water plays an important role in global ocean circulation and climate and yet its formation is also highly sensitive to climate change. This project will analyse new seafloor, core and water samples from the understudied Cape Darnley, East Antarctica, collected on a voyage in early 2022. This new data will be used in combination with an improved high resolution regional ocean model, to understand modern and ....Is there a climatic tipping point for Antarctic Bottom Water formation? Antarctic Bottom Water plays an important role in global ocean circulation and climate and yet its formation is also highly sensitive to climate change. This project will analyse new seafloor, core and water samples from the understudied Cape Darnley, East Antarctica, collected on a voyage in early 2022. This new data will be used in combination with an improved high resolution regional ocean model, to understand modern and past Antarctic Bottom Water formation under different climate states (warmer and colder than present), to determine if there are climate tipping points for the shut down of Antarctic Bottom Water formation. The anticipated benefits include a better understanding of future climate change on this important water mass.Read moreRead less

Back to the Future: Interglacial Warming and the West Antarctic Ice Sheet . The Antarctic is highly-sensitive to abrupt changes caused by the passing of tipping points within the climate system. Crucially, the instrumental record is too short to resolve major uncertainties surrounding future warming. The Last Interglacial (125,000 yrs ago) was 2°C warmer than today and experienced 6-11 m higher global sea levels. The role of Antarctica is vital for constraining sea-level projections. This Austra ....Back to the Future: Interglacial Warming and the West Antarctic Ice Sheet . The Antarctic is highly-sensitive to abrupt changes caused by the passing of tipping points within the climate system. Crucially, the instrumental record is too short to resolve major uncertainties surrounding future warming. The Last Interglacial (125,000 yrs ago) was 2°C warmer than today and experienced 6-11 m higher global sea levels. The role of Antarctica is vital for constraining sea-level projections. This Australian-led international project aims to determine the mechanisms and impacts of past interglacial Antarctic warming up to 2°C (relative to pre-industrial). Innovative techniques integrating horizontal ice cores and high resolution marine records will help identify polar tipping points and better plan for impacts in Australia.Read moreRead less
