Yeah I would be about 157 years old, I doubt I willsee that, then again I would imagine at some point Dykes and other barriers would go up,and by that time we will be getting a lot of water out of the sea by desalination for drinking purposes,that may slow things down a bit.
The Qattara Depression is only one such candidate for such a relatively simple diversion project. Death Valley, California (though much smaller is another). So is the much larger Caspian Sea. A mere 2200 years ago, much of the northermost parts of North Africa were subtropical marshlands and humid jungle not unlike today's Yucatan Peninsula in Mexico. This "global warming" was still evident 1000 years later when our viking ancestors were building colonies in what is now Greenland and Newfoundland, most of which were abandoned when the earth went into the current cooling cycle about 1100 a.d.
All the polar ice is not going to melt and raise the ocean levels. Much more of it would be absorbed into the atmosphere, consumed by vegatation and dropped onto the deserts in the form of rain, much as planting ivy along the wall of a home draws excess moisture from the soil.
ROTFL! San Francisco floods, put up dykes!
