In contrast to shrinking sea ice in the Arctic, sea ice in the oceans surrounding Antarctica has been more extensive on average in recent years than at any other time in the satellite-observed record. There is not a consensus on the causes of Antarctic sea ice trends or regional variability, and observed patterns are not well represented in Earth system models. The goals of this workshop include to examine the observational record of Antarctic sea ice variability; to further understanding of the processes governing the decadal-scale changes and recent surge in Antarctic sea ice extent; to assess projections of future Antarctic sea ice trends; and to identify ways to improve understanding and modeling of recent and future Antarctic sea ice variability. A summary report will be written based on the workshop’s presentations and discussions. This report will not include consensus conclusions or recommendations, but will contain a record of key points emerging from the workshop.
