Antarctic sea ice plays a crucial role in the ecosystem and physical environment of Antarctica and the Southern Ocean. Since the ice reflects the sun's rays and blocks heat exchange between the ocean and the atmosphere, it is critical to our weather and climate. Therefore, we need to understand what affects its extent to improve future climate models and prediction. A new study led by the University of Gothenburg and involving the Alfred Wegener Institute contibuting to this research field has been published in the journal Nature Climate Change.
