New Orleans and Miami doomed by sea rise

Post Reply New Topic

With global warming many cities will disappear under the sea, and for some of them it's already too late.

Actually its several factors causing the demise of the Louisiana boot. Dams further upstream the Mississippi river are impacting sediment transport that resupplies the delta. The Mississippi is also a river and they tend to like to meander, thereby shifting the sight of sediment deposition, meaning the land New Orleans is situated on was going to subside anyways. They're trying to stop the meander though to some effect. The small amount of sea level rise isn't helping the situation either. In essence New Orleans is doomed no matter what.

Sea level rise in the short term, next 1000 years, doesn't really bother me, it's always fluctuated, we just need to learn to not build our cities below a certain point like dinguses. You should have seen North America in the Cambrian, the whole interior was a shallow sea. I feel worse for Bangladesh, their whole country could go under in the next 100 or so years.

These predictions are based on computer models. They are only as good as the data put in. GIGO.

Kind of reminds me of how in the 4th and 5th centuries, northern Germany, much of the Netherlands, and southern Denmark were virtually uninhabitable, spurring the Anglo-Saxon invasion of Britain, as well as expansion southward in Germany, when dry land became a scarce commodity. Those aforementioned areas of Europe in late antiquity bear a striking resemblance to modern day Louisiana and Florida, in that in both cases you're talking about low, marshy land on the sea coast, given to massive flooding. Except in Europe, those northern coastal lands eventually were reclaimed as the water receded, centuries later.
