The consequences of a nuclear free Germany

My UCLA colleague Ann Carlson writing in the Legal Planet environmental blog noted that if Germany eliminates nuclear power they will not meet their 2020 greenhouse gas reduction targets.

Read Ann's OpEd, and then discuss the following.

How do you value the suspected and expected global risks and consequences of increased carbon in the atmosphere versus the risks of a nuclear meltdown, nuclear terrorism, and the problems of storing wastes for a long time?

Don't like how I've framed the question?  Discuss a future that doesn't rely much on carbon and doesn't rely on uranium-based nuclear fission.  What do we need to get there?
