Among the many detrimental impacts from climate change, sea-level rise is one of the most damaging, costly, and devastating. Sea-level change poses particular challenges for coastal communities, and is becoming more prevalent in environmental law. Existing scientific literature about how sea-level change works can often be inaccessible to the people that need it. In addition, each coastal community experiences a unique combination of global, regional, and local factors that define sea-level change.

Sea-level rise is a common denominator that prompts two related but distinct types of coastal migration: (1) wealthy coastal communities that retreat inland to ensure their physical and economic security while encroaching on the neighborhoods of existing vulnerable communities; and (2) vulnerable Native Alaskan communities that relocate inland to ensure their survival while striving to retain their cultural identity.
