First, Holland was last hit by a significant hurricane over 50 years ago. The Gulf gets several every year. New Orleans continues to sink, which will reguire higher and higher levees at the same time that ocean levels are predicted to rise. The Atlantic and Gulf waters are also likely to rise in temperature in the coming years which will not necessarily lead to more hurricanes, but will lead to larger ones. Add to that the natural barrier of swamps and islands that extended out around the delta, once protecting New Orleans, is fast disappearing. Anyone dippy enough to rebuild there can go right ahead. Just don't tie it to my insurance rates when the shit hits the fan.
