I've seen his movie too, and it changed my mind a bit about climate changes, but I am still not convinced we can solve the problem.
Even if Europe and the US reduce CO2 exhaust, China wont worry about the climate at all, and they are growing so rapidly that they will use everything to create power (climatefriendly or not).
And Bush his new vision for space exploration seems more convincing than some notes of the Apollo program in Al Gore's movie.
(but you can have your own opinion of course, after all, I'm not an American.)
