Several Alaskan villages are falling into the sea. This is mostly due to global warming. The permafrost (ground that was permanantly frozen) is melting and the buildings are sinking. Rivers are overflowing. The ice that would form on the shore and protect it from storms is forming later each year.
Here is an example - look at the two pictures, the first taken before a storm and the second one after a storm. They were taken from different angles, so it is hard to look at the shoreline and see the change. Look at how close the metal trashcan is to the edge in each picture.

The cost to relaocate the 3 villages that are not expected to last 10 years:
Shishmaref, ~600 people, up to 200 million dollars
Newtok, ~315 people, up to 130 million dollars,
Kivalena, ~380 people, ~125 million dollars.
These are just the most serious cases.
