The Hurricane / Flooding of New Orleans should be a good wake up call to the US for the near future.
IF water levels were to rise 3 feet over the next 15 years due to Global Melting most US coastal Cities would be in the same situation of needed levy systems and sea walls to protect themselves from rising water levels, let alone hurricanes.
The government, State and city of new orleans new about this potentiality years ago. It was written years ago about what a dead-on stike by a 'cane to New Orleans would do; overwhelm their levy system and flood the city in waste.
The scientific community is still out on whether sea levels will rise and by how much and by when, but a good majority do say they will indeed rise.
I see a repeat of this single event repeated again and again in the coming future of Global Melting until the government puts in some real thought in advance on this, and not handle it like it did with New Orleans with a wait and see it one hits method.
Granted this is still a what if scenario since we don't really know if levels will rise.
But if they do it is guaranteed it will bite us in the ass since the government wil bury it's head in the sand on it.
