You can read more about it here (and here) and perhaps take a dark kind of joy in seeing Gore take his own country to task while gently reminding delegates from the rest of the world that there isn't much time left in office for that guy and that they should plan under the assumption that the next president will be more on board with dealing with climate change. Canada didn't go unscathed either, nor should it when you look at Harper's awful approach.
Addendum: Check out this video with Gore outlining 15 ways for the individual to help out and also display the great sense of humor I suspect he had surgically implanted about three years ago.
