Global sea-level is forecast to rise a metre or so over the next century. In the spirit of dumb-ass geo-engineering proposals to combat global warming, we should consider the most obvious geo-engineering approach to sea-level: pump sea-water into endorheic basins (that is, areas which don't drain into the global ocean), such as the basins of the Caspian Sea, the Aral Sea, Lake Chad, Lake Eyre, and the Tarim basin. These five alone have a combined surface area of about ten million square kilometres, and could easily contain the 4e14 cubic metres of water of a one-metre global sea-level rise.
Exercise for the reader: list five insurmountable obstacles to this cunning scheme.
