Climate and polar researcher Alexander Haumann from the SO-KLIM research group at the Alfred Wegener Institute (AWI) and Ludwig Maximilian University of Munich (LMU) is featured on the BR and ARD Sounds podcast "IQ – Science and Research." The conversation focuses on the latest findings on the decline of Antarctic sea ice and its implications for regional warming, ocean circulation, and the global climate system. The podcast is available in German only.

The ongoing discussion about the unusually rapid decline of Antarctic sea ice is being enriched by new scientific findings. In a series of recent publications in Nature Climate Change, PNAS, and Science Advances, SO-KLIM researchers Alexander Haumann, Theo Spira, and colleagues investigate the processes driving the loss of Antarctic sea ice and the associated changes in the Southern Ocean. Their work provides important insights into the complex interactions between the ocean, atmosphere, and sea ice, improving our understanding of their role in shaping the global climate system.
