Cost estimate for infrastructure protection in Native communities against erosion, flooding, and permafrost thaw.
Reduced Arctic sea ice increases open-water area, which allows storm-driven waves to travel farther and cause greater coastal damage.

Mechanism linking sea-ice loss to intensified coastal wave impacts and erosion.
Thawing permafrost increases coastal erosion because thawed, unconsolidated soil is more easily washed away by waves and storm surge.
