The main attraction, however, is the beautiful blend of awesome digital animation, and personal reflections from Gore that add a very nice human element to the film. The way the film mixes the autobiographical elements: from Gore in a classroom in 1968, listening with rapt attention to the great geochemist Roger Revelle explaining the first few years of data on carbon dioxide increases in the atmosphere to the Al Gore on the family farm, talking about his father's tobacco business, and how he shut it down when his daughter (Al Gore's sister) got lung cancer: is simply phenomenal. The natural elan with which Gore carries off his acting makes us realise that here is a man who he is clearly in his element here, talking about something he has cared deeply about for over thirty years.
What was most heart warming to notice was the efficient manner in which the film handles science, including reference to some of the very latest research that is going on in contemporary times. Not only are discussions of recent changes in Antarctica and Greenland expertly laid out, but Al Gore also does a very good job in talking about the relationship between sea surface temperature and hurricane intensity.
