The Adaptation Actions for a Changing Arctic (AACA) initiative provides combined stakeholder engagement and science-based information that can ultimately be incorporated and interpreted into useful and useable knowledge for making effective adaptation actions within a rapidly changing Arctic. This report presents an overview of the findings of the AACA Bering/Chukchi/Beaufort Region pilot study for policy-makers.
This Summary for Policymakers presents key findings and implications of the second SWIPA assessment, conducted from 2010 to 2016 and published in 2017. SWIPA focuses on changes to the Arctic cryosphere (the portion of Arctic land and water that is seasonally or perennially frozen), and the implications of those changes.
