COP30 Video of the Week: Emerging Evidence of Abrupt Changes in the Antarctic Environment

Changes in Antarctica can trigger fast and cascading impacts, often with global consequences. Multiple abrupt changes in the Antarctic environment now span across Antarctica’s ice, ocean and ecosystems. The interconnections between these systems amplify the risks of exceeding tipping points. Speakers included Dr. Nerilie Abram, Australian Antarctic Division; Dr. Ariaan Purich, Monash University; Dr. Matthew England, University of New South Wales; Dr. Jan Strugnell, James Cook University; and Dr. Barbara Wieneke, Australian Antarctic Division. They highlighted emerging evidence of abrupt changes in the Antarctic environment and discussed the policy responses needed to limit further “surprises” and irreversible loss.
