COP29 Video of the Week: Antarctic Sea Ice at a Crossroads – Status Quo and Future Implications

Since 2016, Antarctic sea ice has remained below the long-term average, with extreme lows in recent summers and winters. These extremes impact terrestrial and marine ecosystems, heat and nutrient distribution, ocean circulation, and expose the margins of the Antarctic Ice Sheet to greater wave and storm activity. Speakers included Stefanie Ardent, Alfred Wegener Institute; Will Hobbes, University of Tasmania; Robbie Mallett, UiT The Arctic University of Norway; Jacqueline Stefels, University of Groningen; and Petra Heil, Australian Antarctic Division. They discussed the current state of Antarctic sea ice, its global climate and ecosystem impacts, and their implications in recent climate projections in an open dialogue with policymakers and other stakeholders. Note: some portions of this on-site video have competing noise, but turning on closed captions (button in the bottom right corner) can help.
