Abrupt Southern Hemisphere Climate Change: The Role Of The Southern Ocean Thermohaline Circulation

点击翻译按钮获取中文摘要

Australia's climate is extreme, with harsh droughts, severe bushfire seasons, climate change, soil loss, and salinity all posing potentially enormous socio-economic challenges over the next ten-fifty years. Research into climate change and climate variability is thus highly significant for Australia, and will underpin efforts to protect our biodiversity and ensure the nation's environmental sustainability. We propose to launch a major new study of the stability of the Southern Ocean's thermohaline circulation and its role in global climate. This work could have significant long-term benefits for those sectors of society sensitive to shifts in climate; including agriculture, energy, freshwater supply, health, and tourism.
