How much CO2 is produced by the world today? How much CO2 would be produced to create the uranium if we were to go totally nuclear? Which is better? Have you heard of fast breeder reactors, by the way?
20000 years? Where did you get that from? It is stable as soon as it if vitrified. 50 years.
As for your final point, wise up. Al Gore's companies are not set up to invest in anything to solve the climate change "problem." He has set himself up with some HEDGE FUNDS. I have worked for enough hedge funds to know where their interests lie. His companies are there to trade derivative, financially engineered products. Another bubble. If Al Gore was investing in scientific research, or engineering companies, then I would applaud him. But he's not. Just another set of financial instruments to scam the world with. And you question my values?

Who mentioned Al Gore? If you think I'm going to argue your misunderstanding of the climate change debate, by reacting to your obvious personal dislike for another human being, then you are wasting your time. I have no respect for politicians, as far as I can see their only interested in making money themselves, whether it's from exploiting the climate change disaster, or by fighting illegal wars, trading in Oil, coal, uranium and other limited resources.
Wind and Tidal do work. Try telling the countries that are already getting their power from renewables, that they can't. You'll be laughed at. There are several countries that get their electricity from renewables.
As for the length of enriched Uranium half-life, you are correct, I got it wrong. Here's a link to the real truth.

The fact is that climate change IS happening, whether you want to argue about what is making it worse or not is irrelevant, nevertheless it makes more sense to do something about not making it any worse, than to stick your head in the sand and arse in the air.
