In An Inconvenient Truth Gore uses visual media to address his point to the fullest. If he had simply used text to convey his message both the live audience and movie watching audience would have become bored with his presentation and would have become disinterested. One of the best examples of this was when he showed pictures of places around the world and what was actually happening right now because of global warming. By seeing what global warming is doing right now people see that they have to take action as soon as possible and cannot put off the problem any longer. The videos of the glaciers were also very powerful and appealed to ethos a bit. People see the beauty of glaciers in the Arctic and Antartic and do not want that to be diminished at all.
I also think the way the graphs were presented was very effective. A small detail was that the graphs were slowly drawn out on the screen instead of being put up all at once. What this did was not let the audience know was what was coming next and made it shocking when the graphs sometimes shot upwards and showed how hot the earth was getting, or the level of CO2 emissions in the atmosphere.
The cartoon he used was also used effectively. It not only gave the audience some comic relief, but also something else to look at besides graph and Gore himself. It is important to visually stimulate the audience in some way besides diagrams and photos, just as it is important as it is to have those photos and diagrams. Gore demonstrated this by using the cartoons at effective intervals and at times when they were best utilized.
