When New Orleans was "established" it

wasn't below sea level. A

lot of the present day city was built below sea

level. =A0 Some engineer had the bright idea of

pumping it out to extend the size of the city.

Yes, New Orleans has sunk over the past 100

or so years, along with the levees.

(I see this as a college student type document to try to explain what
might happen with predicted change in patterns caused by global warming
etc. Ive seen all sorts of "expert" predictions and possible results
many times and they all seemed to have valid background theory but in
reality.. like most things on paper looked good but with no REAL SOLID
proof figures, statistics and charts can be made to say anything. The
figure of 9mm subsidence per year equates to 90cm over 100 years, or
3ft. )

I concur with the above poster regarding the provided text. Glaciers
melt faster than that.
