Klaus Jacob. "Time for a Tough Question: Why Rebuild?". Washington Post. 6 Sept. 2005 - global sea levels have risen less than a foot in the past century, and will rise one to three feet by the end of this century. Yes, there is uncertainty. But there is no doubt in the scientific community that the rise in global sea levels will accelerate.
What does this mean for New Orleans's future? Government officials and academic experts have said for years that in about 100 years, New Orleans may no longer exist. Period.
Walter Youngquist. "Should New Orleans be Rebuilt?". NPG Internet Forum - In 2100, will New Orleans still be holding fast? Look at the photo of the sloshing levee above and then ponder the low end of the projections of rising sea levels in last year’s reports from the Intergovernmental Panel on Climate Change. Set aside the question of whether warming will intensify hurricanes. Just look at the picture and think of an extra foot of water. How high will people willingly build such walls? Who will pay? I guess we’ll find out.
John Burton, comment on Dot Earth, cited in 2008 New York Times article - After we experience the human suffering and the national financial costs from Katrina and Gustav, will we have a debate on the wisdom of rebuilding in coastal waters? We know that gradually and slowly global warming will increase such flooding.
