If New Orleans really does get washed away, perhaps it will lead to a greater public awareness of scientific warnings of natural disasters.

"Remember New Orleans? Let me talk to you about ice caps..."

Then again, as a culture, we don't seem to respond to threats before they happen. We all knew this was a possible future for New Orleans, but it's easier or cheaper just to deal with threats as they happen than to move an entire metropolis 100 miles inland (away from most of the things that define it as a city). It's just so frustrating to think about when part of the calculus includes human lives.
