ACEAS is a collaboration between Australian universities, government agencies and international research institutions. We connect new knowledge of East Antarctica and the Southern Ocean within the research community and with governments, industry and academia.The evolution of East Antarctica and the Southern Ocean affects most of the global population. Changes in the area both exacerbate and mitigate the impacts of climate change on physical environments and ecosystems. Industries, infrastructure, housing and lifestyles will all change as the ice sheet increasingly discharges more ice into the Southern Ocean. Ocean acidification will impact the ocean food web and fisheries. The changing sea ice will shift Australia's weather and climate.The exact changes that will emerge, the timescale over which they will occur, and the impact they will have, remain highly uncertain. Many tipping points in this region are poorly understood—which can potentially lead to unwanted surprises for humanity.The Centre will build a confident understanding of tipping points in the Antarctic region, the timescales over which they could be passed, and the consequences of passing them.The research is planned and conducted with a clear eye on guiding decisions made by domestic and international governments, recommendations made by policy-informing bodies, and preparations made for the impact of climate change by all sectors of society.
