Warmer water is flowing toward the East Antarctic ice sheet, according to our alarming new research that reveals new potential drivers of global sea level rise. Author Laura Herraiz Borreguero Physical oceanographer, CSIRO Alberto Naveira Garabato Professor, National Center for Oceanography, University of Southampton Jess Melbourne-Thomas Transdisciplinary Researcher & Knowledge Broker, CSIRO The research, published today in Nature Climate Change, suggests changes in water circulation in the Southern Ocean could jeopardize the stability of the East Antarctic ice sheet. The ice sheet, the size of the United States, is the largest in the world. Changes in water circulation are caused by shifting wind patterns, and are linked to factors including climate change. Warmer waters and rising sea levels can damage marine life and threaten human coastal settlements. Our findings underscore the urgency of limiting global warming to below 1.5℃, to prevent the most catastrophic

Alarming stories from Antarctica are happening more often than ever before; surface ice is melting, floating ice sheets are collapsing and glaciers are flowing faster into the ocean. Antarctica will be the biggest source of future sea level rise. But scientists don’t know exactly how this melting will happen as the climate warms. Our latest research looks at how the Antarctic ice sheet has advanced and retreated over the last 10,000 years. It holds strong warnings, and perhaps some hope, for the future. Current imbalance Future sea level rise presents one of the most significant challenges of climate change, with the expected economic, environmental and social impacts on coastal communities around the world. Although it may seem like a distant problem, change in Antarctica will soon be felt at our doorstep, in the form of rising sea levels. Antarctica is home to the single largest ice mass in the world: the Antarctic ice sheet. This glacier’s ice body is several kilometers thick, l
