Save London From a Sudden Glacial Melting?

There are a few million cubic miles of water trapped in the ice-caps that line our planet's poles. If all of it were to melt in a matter of a few short years (somehow), London would surely be left under the new sea-level.
Quick facts: Trafalgar square has a 21m elevation relative to the present sealevel. If all the ice covering Antarctica, Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet).
What can be done to save London, lest Big Ben is to sound its bells underwater? Can Britannia once again rule the waves?
