Taking the exact opposite tack -- people have worked out a fairly simple plan to build a canal from the Mediterranean to the Quattara Depression (in Libya). Any rise in sea level (although, as you point out, any such rise seems unlikely), but any such rise which did occur could be easily sent out into the depression where it would quickly evaporate. Substantial hydro-electric power could be generated as well.
Basically, no sensible person should worry about any rise in sea levels. It ain't gonna happen.
