Peak NOLA?

I asked this sort of as a joke last week but it really might be worth exploring.  At what point do people currently investing in the red hot New Orleans real estate market begin to consider cashing out before the long term value starts to crash?

The collapse of large parts of the ice sheet in West Antarctica appears to have begun and is almost certainly unstoppable, with global warming accelerating the pace of the disintegration, two groups of scientists reported Monday.

The finding, which had been feared by some scientists for decades, means that a rise in global sea level of at least 10 feet may now be inevitable. The rise may continue to be relatively slow for at least the next century or so, the scientists said, but sometime after that it will probably speed up so sharply as to become a crisis.

Of course, "the next century or so"  is more of a mileage-may-vary sort of proposition.  We probably aren't on the generous side of that.
