Last fall, two towns at opposite ends of the country entered a new kind of contest run by the federal government. At stake was their survival: Each is being consumed by the rising ocean, and winning money from Washington would mean the chance to move to higher ground.

It was about to lose its drinking water, its school and maybe even its airport. Its 350 or so residents had been trying to move to safety for 20 years; in 2003, they obtained new land, about 10 miles to the south.
