Another idea that may have merit is a global pipeline fund to flood the deserts of the world with seawater.

There are many areas of the world that are inland deserts well below sea level, for instance the Caspian Basin, the areas surrounding the Dead Sea, areas of the Australian desert and many others. Pipelines and canals could be built from the ocean, funded by a every nation on earth as everyone would benefit from the lowering of sea levels. The pipelines could be siphon driven with nuclear powered pumping stations perhaps.

The benefits would be large- as well as mitigating the effects of rising sea level (enough to counteract melting ice) you would also create inland marine ecosystems, increase evaporation and precipitation and possibly create new forested areas in the desert, which would remove large amounts of carbon from the air over time.

It would be a huge engineering project over hundreds of years, but it looks like similar things are already happening: The news story below talks about a pipeline being planned to refill the Dead Sea.

This might be easier engineering-wise, although it does nothing to reduce the source of the problem- CO2 emissions.

You can draw some power until the water levels equalize.  I don't think the Baku, Azerbaijani folks are going to be real happy to hear about this plan though.  They're kinda' in a mess already.
