Automotive New Orleans and Global Warming

Now this is a harsh thought, and I do sympathize to all those people that lost so much, but given the realities of global warming and climate change. Are we going to look back in 50 or 100 years and say "New Orleans was the first great city we lost" See the Union of Concerned Scientists for a discussion on Global Warming Lending Strength to Hurricanes so the question is does it make sense to rebuild?
