Sim sent me a great compilation of direct quotes from the world leaders in climate science, business, and the likes. It's kinda past the point where this can be "discussed" any longer, we're 20 years behind where we should be on the attack front.

The other great, in fact AWESOME resource, is of course ye olde how to talk to global warming sceptic articles page. He's got a master page, with topics more easily categorised now also.
Don't forget to do something about it at home.
