Antarctica and the Southern Ocean play important roles in the global climate system, with their crucial influences on, e.g., sea level, ocean circulation and heat/carbon storage. They are also the least known components because the precise understanding of the processes requires observations of various interactions, such as those between ocean, ice shelf and ice sheet, in the harshest conditions on the Earth's surface. Recent advancements in direct and satellite observations and data analyses have suggested significant changes in the Antarctic. However, as the spatial and temporal scales of the changes are diverse (from sub-annual to over millennial), significant challenges remain in their understanding and modeling.

This session will invite several presentations that address the Antarctic environmental changes in the past, present and potential future, and the importance of interdisciplinary and international observations and modeling for better understanding and projection of the Antarctic and their influences on the global environments.
