Appendix D
Workshop Agenda and Participants

January 11-12, 2016
University of Colorado Boulder
CIRES Auditorium-Room 338
216 UCB
Boulder, CO 80309

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.

The sea ice surrounding Antarctica has increased in extent and concentration from the late 1970s, when satellite-based measurements began, until 2015. Although this increasing trend is modest, it is surprising given the overall warming of the global climate and the region. Indeed, climate models, which incorporate our best understanding of the processes affecting the region, generally simulate a decrease in sea ice. Moreover, sea ice in the Arctic has exhibited pronounced declines over the same period, consistent with global climate model simulations. For these reasons, the behavior of Antarctic sea ice has presented a conundrum for global climate change science.

The National Academies of Sciences, Engineering, and Medicine held a workshop in January 2016, to bring together scientists with different sets of expertise and perspectives to further explore potential mechanisms driving the evolution of recent Antarctic sea ice variability and to discuss ways to advance understanding of Antarctic sea ice and its relationship to the broader ocean-climate system. This publication summarizes the presentations and discussions from the workshop.
