Lead authors from the Nature paper covered in last week’s Capsules described how changes in Antarctica can trigger fast and cascading impacts, often with global consequences. Multiple abrupt changes in the Antarctic environment are now unfolding – spanning Antarctica’s ice, ocean and ecosystems – and 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 losses from the Antarctic region.
