Not so sure, weather last six months been so extreme and everyone is being affected. With the tsunami pointing a big finger at nuclear as dangerous, and with the weather doing what it's doing, it seems people are suddenly going to realise climate change is here to stay and it's going to affect everyone, and nuclear isn't the answer.
Might see a big green push in our lifetimes still I would guess.
Same thing happened to lead and CFC's, once the problem was understood and some consequences arrived the entire world took action to solve it. And they did.
All we need now is a few natural disasters in the developed world and things will change rapidly from the bottom up.
