As Antarctic sea ice continues its dramatic decline, we need more measurements and better models to predict its future

26 September 2023

After two seasons of record-breaking lows, Antarctica’s sea ice remains in dramatic decline, tracking well below any winter maximum levels observed since satellite monitoring began during the late 1970s.


The annual freeze-thaw cycle is one of Earth’s largest seasonal changes but it’s difficult for climate models to predict accurately. Scientists suggest 2023 could mark a huge shift for Antarctic sea ice. 

UC Associate Professor for Remote Sensing and Glaciology Wolfgang Rack and his co-authors explain what anomalies in Antarctic sea ice thickness mean for our world, on The Conversation.
