On the other hand, an ark might not be a bad idea

Here's a report on Louisiana's vanishing coast put together for The Weather Channel by Katy Reckdahl.

Over the past 80 years alone, experts estimate that about 1,900 square miles of Louisiana coastal land have washed away. The state loses a football field-sized area of land every 45 minutes. Flooding has increased markedly, causing residents to raise their homes again and again. Many homes are now set on stilts more than 13 feet in the air.

But elevated houses only postpone what now seems inevitable: the complete disappearance of south Louisiana’s small coastal fishing communities, most of them populated by families who have spent their lives pulling shrimp, crabs and oysters from the water that now threatens to submerge them.
