i have not seen the movie but i have seen the interview of al gore about the movie. personally while the message is good i think he framed it badly, it's going to give the impression that you can have your cake and eat it too.
if we do have 10 years left before we reach the point of no return(which i think we do) then there is really not much that can be done. it will take longer then 10 years to unseat the current people in power, no not the politicians the lobbyists who pull their strings. also i don't think the cfc analogy works here, that was a problem limited to a few items, this one is linked to a whole lot more.
I have a very hard time thinking we have 10 years left, as in the last few years the science has revealing that things are much worse than was previously thought.  Really, we're not going to stop burning coal, in fact we will burn more of it.  The only hope is to affect the co2 levels via direct intervention, but that would require a small miracle considering humanity's consistent lack of foresight when it comes to the side effects our technofixes.
