Coastal flooding could disproportionately affect Native Alaskans, who make up the majority of residents in Alaska’s remote coastal villages along the western and northern coasts where topography is relatively flat.

By 2050, Alaska's 100-year coastal floodplain is projected to expand by more than 15,000 square miles, by far the most land of any state.

Today, Alaska has 17,000 people at risk of coastal flooding. By 2050, an additional 3,000 people are projected to be at risk due to rising seas.
