The SEARCH Sea Ice Action Team’s First Knowledge Exchange Workshop on the Impacts of Arctic Sea-Ice Loss took place over two days in Washington, DC during September 2016. Over 30 scientific experts, representatives from government and non-governmental organizations, arctic residents, and other stakeholders defined and addressed important societal questions raised by sea-ice loss, and explored new approaches and partnerships for advancing awareness and understanding of the associated impacts. The workshop exchanged best practices and opportunities for communicating with various audiences—policymakers, the media, local arctic residents and stakeholders, and other science disciplines. Participants discussed the state of scientific knowledge and engagement across three themes related to arctic sea-ice loss: arctic marine ecosystems, lower latitude weather, and human activities in the Bering, Chukchi, and Beaufort Seas. Participants agreed that the newly initiated Sea Ice Action Network, supported by SEARCH and guided by the Sea Ice Action Team, will provide a promising collaborative approach to communicating the implications of arctic sea-ice loss, sharing diverse perspectives, and facilitating more sophisticated discussions on effective responses.
