A more interesting plan might be to convert all those useless atomic weapons to nuclear fuel to power a new generation of breeder reactors. Let's go over to at least 20% nuclear power. That'll go a large ways towards balancing our CO2 emissions.
I assume you mean 20% worldwide; the US is at roughly 21% nuclear, and Europe is 42%. (Figures from 2001)
There have been programs to do this--run power plants with weapons, it's certainly a good idea.
