From the Brookings Institute site:

“For thousands of years, Arctic peoples have migrated in response to changing environmental conditions. But today climate change is putting unprecedented pressure on those indigenous communities. Temperatures are rising much faster in the Arctic than in the rest of the world, raising questions about the extent to which significant numbers of indigenous people will move away from their traditional habitats and whether they will be able to maintain their cultures and livelihoods. For the 400,000 indigenous people in the Arctic these are not only questions of adaptation but also of culture and survival.”

The issue of internal displacement also lead to questions of governmental and administrative responsibilities. If an Indigenous community is displaced because of rising waters, will the government set aside new lands? Where would they be? Would current subsistence and cultural needs also be considered? Some serious concerns for communities in Alaska as well as Indigenous communities around the world.
