It appears to have disappeared from the Sun-Sentinel web site, but Roger Pielke Jr has excerpted the story that Katrina’s winds were only Category 1 force when they struck New Orleans’ levees. As the article suggests, this raises the question of what would happen to a rebuilt New Orleans if it was hit by a Category 4 or 5 storm. It should also prompt Louisianans to ask exactly why structures designed to withstand Category 3 failed when hit by a measly Category 1. This is more and more evidence that, when it comes to disaster, global warming ain’t got nothing on incompetence and corruption, which destroy resiliency.
